does anyone have a program/sub-routine/mod etc. to calculate the mod 10 check-digit for a numbers with varying sizes.
I have a MOD10 routine for barcode check digits (for example, UPC/EAN codes.) I may also have one for credit card numbers somewhere, but it'd be old and yucky and you probably wouldn't want it :)
It would help if you'd specify WHICH Mod10 you're looking for. Barcodes and Credit Card numbers both use a check digit called MOD10, but it's a COMPLETELY different algorithm.
There are probably other things that use the term "Mod10" as well, but mean something different from what oyu're looking for.
So please clarify what you're looking for... thanks
