Luhn algorithm: Applications, Uses & Strengths and weaknesses

The Luhn algorithm or Luhn formula (creator: IBM scientist Hans Peter Luhn), also known as the "modulus 10" or "mod 10" algorithm, is a simple check digit formula used to validate a variety of identification numbers. The purpose is to design a numbering scheme in such a way that when a human is entering a number, a computer can quickly check it for errors.
