To calculate IBAN checksums, you convert the bank account identifier to a number, take the modulus of 97, and then subtract that from 98. Example: ABNA01234 → 10 11 23 10 0 1 2 3 4 1011231001234 mod 97 = 38 98 - 38 = 60 What is the purpose of that last step?
Same result would be achieved by adding 1 or even 10, which seems more elegant?
