I have 2 blocks of numbers, the first block contains 9 digits the second 8
digits where the last digit in each block needs to be a MOD 7 check digit.
I need to use these numbers in my Primary Key when adding new records, I can
easily get the MAX number + 1 but no idea how to get the last MOD 7 check
digit. I see some tags for MOD 10 but cant find any info on MOD 7. Any
idea's?
Example:
Block 1 (x = MOD 7 check digit)
15400006x
15429999x
Block 2 (x = MOD 7 check digit)
9880000x
9889999x
Thanks,Adrian
