How To Calculate Check Digit (MOD 10)

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.


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!

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!

Seperate 2 Digit Number Into 2 Single Digit Numbers

MOD Function
what the hek the MOD function is supposed to do. According to the MS Help file, it returns the remainder of a number divided by another number. Now, when I was in school, the remainder was pretty much anything after the decimal. That doesn't seem to be the case in Excel, however.

For the examples here, let A1 equal 5.

The formula =MOD(A1,2), as I see it, should return 5 since 5/2 equals .50, but it doesn't; it returns 1.
Further, 5/3 equals .67, but =MOD(A1,3) returns 2 (what, is it rounding?)

There's a lot of talk about MOD being used to return even/odd results, but does this work when the MOD function uses 1 or 3 (or higher) as the divisor?

Mod Function Works Wrong
I was trying to explain modulus to someone and they wanted to know why you can "flip" symbols mod(-6,7) = 1 in Excel. So I got to explaining that -6 Mod 7 is the same as -6-(|-6/7|)*7 which is how you get 1.

And that's when I realized... |-6/7| = 0 not -1. Then I looked in VBA and sure enough -6 mod 7 = -6. Apparently the problem boils down to the Integer conversion. Excel is performing the integer coversion by rounding down (INT) wheras VBA appears to be using CINT.

So here is how it work out in excel:

Implement The Mod Function In VBA?
VBA 2003 does not support MOD (modulo arithmetic) as a WorksheetFunction, and there does not seem to be a direct MOD function in VBA. I've been dabbling with code that would do the same thing as MOD, so far with no success. Does anyone know how to do this in VBA? I assume it would be some combination of If...Then, Round (up or down), maybe a compare, and perhaps an iteration loop. I would think such a routine would be useful to many people.

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).


98 --> 1998
99 --> 1999
00 --> 2000
01 --> 2001

The thing is sometimes there are characters in column K like "N/A" for instance and the macro crashes since its only designed to take into account numerical and blank cells in column K.

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
01-02-034-05-W2 TO 02-03-045-06-W2

To this:

01-02-034-05-W2 TO 02-03-045-06-W2 ,

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:

01-02-034-05-W2 TO 02-03-045-07-W2
02-02-034-05-W2 TO 02-03-045-07-W2
03-02-034-05-W2 TO 02-03-045-07-W2

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:

01-02-034-05-W2 TO 02-03-045-07-W2 ,
02-02-034-05-W2 TO 02-03-045-07-W2 ,
03-02-034-05-W2 TO 02-03-045-07-W2 ,

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

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.
