LUHN ALGORITHM

The Luhn algorithm (also known as the "modulus 10" or "mod 10" algorithm) is a simple checksum formula used to validate credit card numbers and other identification numbers.

  1. Starting from the rightmost digit and moving left, double the value of every second digit.
  2. If doubling results in a two-digit number, add those digits together.
  3. Sum all the digits in the resulting sequence.
  4. If the total modulo 10 is equal to 0, the number is valid.
