The mathematical formula called Luhn Algorithm is a simple checksum formula used to validate a variety of identification numbers, such as credit card numbers, IMEI numbers, and Canadian Social Insurance Numbers.
The algorithm, which is based on a mathematical formula, is commonly used to distinguish valid numbers from mistyped or otherwise incorrect numbers on credit cards and other identification cards.
The algorithm is a way of making sure that the number you enter is correct. This is done to protect you from mistakes and people who might try to commit fraud.
The Luhn Algorithm is also known as the “mod 10” or “modulus 10” algorithm because it uses a modular division by 10.
It works by looking at a credit card number and performing a mathematical operation on it.
The number is then divided by 10, and if the remainder is 0, the number is a valid credit card number.
If the remainder is not 0, the number is invalid.
