The Luhn algorithm is also known as the "modulus 10" or "mod 10" algorithm. It is a simple checksum formula used to validate a variety of identification numbers, such as credit card numbers. It was designed to protect against accidental errors and "not" malicious attacks.
In this video, we have covered how the algorithm works and a few limitations of Luhn's Algorithm with examples. I hope the explanation is simple to follow through.
Thank you for your time.
