Here's my dilemma:
I need to figure out the algorithm to a checksum. I've got multiple examples of numbers and the checksums, but I haven't been able to determine how its calculated.
The format:
023303337106637707 51125
Where "023303337106637707" is the first part, and "51125" is the checksum that I need to be able to get.
I've been looking into using THC's Shagg program, which can generate UPCs, ISBNs, VISA credit card numbers, etc. If anyone has any experience with Shagg, that'd be helpful.
But basically I was just wondering if anyone here has done anything like this before, and if so, how?
