How to calculate a check digit in excel. The details to calculate this are as follows:
All variables in the calculation are positive integers.
We take each integer of the pro number and multiply it by a value and sum them to get a total.
An Example: 8 Digit Pro Number: 66988757
Pro Number: 6 6 9 8 8 7 5 7
Position in the Pro Number: 1 2 3 4 5 6 7 8
Multiply each digit in the pro number by (10-position) in the number, to achieve a sum.
Using our example pro again:
6*(10-1) + 6*(10-2) + 9*(10-3) + 8*(10-4) + 8*(10-5) + 7*(10-6) + 5*(10-7) + 7*(10-8)
6*9 + 6*8 + 9*7 + 8*6 + 8*5 + 7*4 + 5*3 + 7*2
54+ 48+ 63+48+40+28+15+14 = 310
Take the Sum of the previous calculation and divide it by 11
310/11 = 28
(Actually, it's 28.181818, but since we're working with integers, we truncate everything behind the decimal).
Figure a remainder by multiplying the quotient by 11 and subtracting from the sum.
Remainder = 310 - (28*11) ---> Remainder = 310 - 308 ----> Remainder = 2
Check Digit = 11- Remainder
Check Digit = 11 - 2 ---> Check Digit = 9
Note: if the check digit is 10 or 11, need to subtract 10 from the Check Digit.
I know you can take a number from one cell and combine it with number from another cell and make it one number. What I need to do is the reverse. Take a two digit number in a cell and separate it into single digits in two cells. If you have the number 50 in a cell, then is there a formula that will take the 5 and put it in cell and take the 0 and put it in the cell beside it?
I have a column of 6 digit numbers in excel, and I need to remove the last digit from each number, turning it into a 5 digit number. No rounding, just simply remove the last digit. Each number is different. Does anyone know how to quickly and efficiently remove the last digit from each number? I can convert to alphanumeric string if need be...
My company uses 4 types of barcodes 8, 12, 13, & 14 number barcodes for our products my problem is that I can't figure out how to force the barcode to format properly no matter how somebody enters it if they don't use spaces or put them in the wrong spots, I can't use custom formats because there is 4 different layouts
8 digit should be "#### ####" 12 digit should be "###### ######" 13 digit should be "# ###### ######" 14 digit should be "# ## ##### ######"
these barcodes are in columns L, M, & N also right now 'm using a formula in another cell to verify the barcodes by calculating the check digit and comparing it to the check digit typed the formula i'm using is
How do I create a formula that will calculate a check digit for a 9-digit number using MOD 10? The weighting is 212121212. The problem I am having is that if the sum of the product is in double digits, they must be treated as individual digits.
Example:
Number To Be Calculated: 0 0 4 4 5 5 5 2 5
Weighting: 2 1 2 1 2 1 2 1 2
Sum: 0+0+8+4+1+0+5+1+0+2+1+0
22/10 = 2 r2 10-2 = 8 (Check Digit)
Is it possible to create such a formula? I need to calculate several hundred and do not want to do this manually!
I wanna create a buildin check digit for container numbers
so it will exists out of 11 cells. ( GATU 021097-9 )
is it possible when u type any letter/number in the first cell on a row it automaticly jumps to the next cell, repeating this for the full container number ?
I have a spreadsheet that pulls in a log file after running a macro with 100000eight digit numbers which may or may not have a record in the system. These numbers are produced by using any seven digits and adding a check digit at the end for an eight digit number using the mod function specifically Mod7...=MOD(A1,7) , for example, if cell A1 has 1234567 the mod7 function will produce the check digit 5 then concatenating for the eight digit number 12345675. the next number will be produced by adding 1 to the end of the 7 digit number 1234567+1=1234568 then concatenating again the number with the check digit 6, 12345686. this would be sequential order.
my spreadsheet gets all the eight digit numbers with no record and sorts them in MOD7 sequential order in one column. since the spreadsheet ignores the eight digit numbers with records. my compiled list of numbers have non sequential numbers in the list.
i need a way in VB to loop through 100000 lines (column A) and find the first and last number of a MOD7 sequential range and place the first number in (column B) and the last in (column C).
I have figured a way to do this in a spreadsheet but it takes too many functions and calculations in 100000 lines so the spreadsheet takes too long to open and sometimes crashes!
This is my code. It is for checking that only a 4 digit fiscal year is entered in a cell. The code works fine except it only checks a max of three time. So if the user enters xxx it will prompt for a correct response three times, if xxx is entere a 4th time then that value appears in the cell. I was wondering why this is taking place.
how you can determine if a cel value is a number or a digit
It is actually for a column to determine if it has a heading or not and acordingly y have to count the rows off that "current region" and put some values with a formula next to this column.
Y was testing an expression with this
msg = IIf(target.End(xlUp).Value = "X", "is this a LETTER", "is this a DIGIT")
Well I want to add few numbers in a few number for example I have ten columns containing few cell numbers and i want to add 92 my country code with it. I have tried this by using replace formula but in result it comes in text format from which i cannot use another formula unless text format is removed and for that i have to do it one by on in every single cell. I have attached a sample sheet.
or whatever the number is after A1D, but when AK8 = a value of 1 or 2 or 3...... It comes back as A1D1 or A1D2... How ca I keep the two digits in AK8 to stay and put the value the way I want in AE5 ...
I'm trying to figure out how to setup a worksheet to find the most common 2 digit numbers going vertically from the bottom(cold) to the top(hot) it would consist of 90 digits 0 thru 9
each vertical line would be considered weeks 9 thru 1. week 9 would be the first vertical line of digits on the left. it could also contain the most common 2 digits horizontally. Both 2 digit values would be color coded ex. blue equals most common 2 digit horizontally and green equals vertically. I would also like to color code the most common 2 digit value diagonally as long as it is the most common of either the vertical or horizontal 2 digit. Each number is seperate on the worksheet they would not be pairs. im using excell 2003.
The last digit of a number (can be any demonination but always an integer). I know that you can check the last digit of a number with =RIGHT(A1,1) but I would like to check whether the last digit in number is 1,2,3,4,5 and if so change the whole number to a number ending in 5. If the original number ends in 0,9,8,7,6 then I want it to be changed to end in 9. Is this possible and if so is there an excel function that I could use?? e.g. 143 -> 145 e.g. 1037 -> 1039
I have a cell with a number which is a result of several previous sums. It's a number with 8 to 11 digits. For example: 878567663.
I need to add each digit of the number, and then add again the result until I end up with a single digit. In the above example it'd be (8+7+8+5+6+7+6+6+3=56), then (5+6=11), then (1+1=2) and put the end result (2) in a cell
My main doubt is that I don't know how to use a simple "do while" type structure in Excel to achieve the above.
Questions:
1.) How do I create a formula to do that?. I have seen solutions in this board that let me add each digit but that's it... I need to "reduce" it until only one digit is left...
2.) What about if the lenght of the number is not always the same (fe. in one cell is 8, in another is 11, the next one is again 8...)?
I need a macro where I can highlight a column and change all of the 2 digit years to a 4 digit year (actually, some of the 2 digit years are only 1 digit, e.g. "9" instead of "09").
I have an if then statement that I can use in the column after it, but I'd rather change the actual numbers in the original column, rather than adding another column (and having to keep the original, too).
The statement I had was: =if(A1>=50,1900+A1,2000+A1)
I just copy dragged down to get the cell numbers for the rest of the column... but using A1 was just for an example, here, it's not necessarily going to be in that column. It needs to be just whichever cells I select.
It seems like it should be pretty simple, but I don't know how to word it in a macro.
I am trying to get a formula to return the last digit from a number in a cell as a number.
If the cell (B3) contains a number such as 164 or 34 I want to return a value of 4 and have it be formated as a number.
I have tried =RIGHT(B3,1) and it returns a 4 but I cannot get another formula to recognize it as a number. It shows up in the cell on the left side as text would and if I format it as a number nothing happens it is still on the left and the formula does not work.
I'm trying to search a column that has cells with various length strings. Included in the strange (at random locations) could be possibly be a 7 digit number starting with 4. I want a formula that counts the number of cells with contain that 7 digit number. Is this possible?
I have a cell containing body of an email.How can i check for 15 or 16 digit number in the text and extract it. Basically i am checking for a credit card number in the email and if it is there then i need to extract it to adjacent colum.
Image below has a 500 cells I want to delete the 12 digit number but the numbers that align to the 12 digit was in one cell so it is hard to do manually how to delete it
I am using following formulae to convert 16 digit number to with validation that number is not exceeding 16 digits and should always start with "1" else it should give Error with 11 blank spaces
but when I input any number which has a value other than zero e.g. 1009510010000059 its returning result as 1009510010000050 I need validation also in the same formulae
I have this script that does what i need it to do but one thing, I need the script to count the numbers as digits only and not the dashes in the format.
Private Sub Worksheet_Change(ByVal Target As Range) If Target.Count 1 Then Exit Sub If Intersect(Target, Range("I21:I24")) Is Nothing Then Exit Sub Application.ScreenUpdating = False Application.EnableEvents = False If (Len(Target) > 11) Or (Len(Target) < 10) Then MsgBox "Not a valid number of characters, please try again" Target.Value = vbNullString...................
is there a way to convert many entries of dates and time entered in the above way into actual dates and times? is it as simple as making a custom format? if so, whats the syntax?
the entries appear to be the year(4 characters), the month (2 characters), the day of month (2 characters), and the time of day (6 characters, AM/PM)
i dont need the time, so the last part ("120000[0:GMT]") isn't necessary.
I need to extract a set of 5 numbers from a string of characters. The number set I need is always 5 digits long, always starts with a 1, and always begins after a period. But the number I need can occur in different parts of the string:
In each example below I would want to extract only the 10572 portion.
Additionally (if possible) if the cell is blank I don't want anything to show up, and if the string begins with a letter then I don't want anything to show up either.
