How To Calculate Check Digit (MOD 10)
How do I create a formula that will calculate a check digit for a 9digit 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
102 = 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!

Macro To Force Format And Check Barcode Check Digit
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

Sequential Check Digit Validation
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!

Check 4 Digit Fiscal Year Is Entered In A Cell
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. Here is my

Seperate 2 Digit Number Into 2 Single Digit Numbers
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?

Converting 2 Digit Year Into 4 Digit Year
I have 2 digit years (98, 99, 00, 01) that I need to convert to 4 digit years (1998, 1999, 2000, 2001). There is one year per cell. If it was simply a matter of adding 19 or 20 to the beginning of each, I could do that. But since there's a combination of both 19 and 20 that needs to be added and there all intermingled, I'm not sure how to do it. Can a rule be written to add 19 to the beginning except if the current cell starts with a 0, then add 20? The highest year is 2008 (no 2010 to deal with). Example: 98 > 1998 99 > 1999 00 > 2000 01 > 2001

15 Digit Sequence
My question is, a formula was provided to me that add's a comma and a space after a 15 digit sequence of numbers, that formula is: =IF(MID(C378,LEN(C378)1,1)="W",C378&" ,",C378) And what that does is it would change data in a cell that looks like this 010203405W2 TO 020304506W2 To this: 010203405W2 TO 020304506W2 , The formula works great, thanks to the help of the posters! However I just ran into an issue, what if I have a set of data in a cell that looks like this: 010203405W2 TO 020304507W2 020203405W2 TO 020304507W2 030203405W2 TO 020304507W2 And I need a space and a comma at the end of each sequence, so the above would change to this after the formula is applied: 010203405W2 TO 020304507W2 , 020203405W2 TO 020304507W2 , 030203405W2 TO 020304507W2 , Now the data in the cell is wrapped so it lists one set of numbers, then the next set, then the next set as seen above.

Sorting By First Digit Only
I am trying to sort a spreadsheet in descending order of a certain column. I have been able to do so quite easily in the past. However, for some reason, when I am trying to sort it now, it is sorting based only on the first digit of the number in the cell. For example, the order after sorting may end up as 90, 9, 9, 82, 8, 8, 8, 74, etc. I don't know what happened to cause the change, or how to fix it.

Change Last Digit Of A Number To 5 Or 9
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

2 Digit Number Combination
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 it would look like this 4 0 3 9 0 4 3 3 2 9 2 5 6 5 6 9 6 6 8 9 9 3 1 0 2 9 8 1 6 7 5 9 9 8 2 5 2 7 2 2 2 8 5 1 3 0 1 4 7 4 7 6 0 9 3 5 6 4 3 3 0 4 4 7 8 8 1 8 5 7 8 7 5 4 1 8 6 1 1 5 1 6 3 0 0 7 2 4 7 0 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.

Add/Sum Each Digit In Long Number
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...)?

Two Digit Year Changes On Import
I am importing data from a .csv file. The file contains dates like 02/15/40. The year is 2040, not 1940. Excel doesn't seem to use the Control Panel > Regional Settings change when I open this file. I have my Regional Settings set to 2000 => 2099 to change to a two digit year. If I open a blank worksheet and type in 2/15/40 in a cell...Excel does the correct conversion to 2040. However, when I open a .csv file it considers it 1940.

Extract 5 Digit Number From String
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. 5194003.10572.N 5194003.10572.R 5194003.1.0010785.10572 7500008.N.5999900.10572 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.

Convert The Digit In Specific Format
I work in the flooring industry and the format we use for cuts of carpet/vinyl is 403 (for 40.25 feet), etc. So we are trying to create an excel spreadsheet that will add up these cuts. Right now it's kind of a mess because we have decimals in a column we will be hiding and are converting that to our industry format. The formula I am having trouble with is as follows: =MID(A18,1,FIND(".",A18)1)&""&MID(A18,FIND(".",A18),3)*12 The problem is that whenever the totals end in zero, the formula won't convert 40.00 to 400. It gives me an error every time. If the total is 40.25 it will convert it to 403 just fine.

Return Last Digit In Cell As A Number
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.

Convert X Digit Number To Letters
Nice to meet you all. I'd be grateful for any help I could get on this as I have tried it and I'm a bit stumped... What I need to do is the following: Convert a 4 digit number (e.g. 1234) in a single cell to a 4 letter string (e.g BCDE) and have the output appear in another cell. The conversion should be as follows: 0=A 1=B 2=C 3=D 4=E 5=F 6=G 7=H 8=I 9=J 0=K So, for example, 3678 in one cell should be converted to DGHI in the target cell.
