= Luhn mod N algorithm
{wiki=Luhn_mod_N_algorithm}
The Luhn algorithm, also known as the "modulus 10" algorithm, is a simple checksum formula used to validate a variety of identification numbers, particularly credit card numbers. However, when you mention "Luhn mod N," you are referring to a generalization of the Luhn algorithm that can be adapted to use different modulus bases (N). \#\#\# Overview of the Luhn Algorithm: 1. **Starting from the rightmost digit**, take each digit from the number.
