Luhn Algorithm Calculator. The Luhn Algorithm (Mod 10) Calculator is a simple tool allowing one to validate numbers and calculate the correct check digit for a given number via the Luhn checksum algorithm.
This calculator calculates digit sequence checksum using Luhn algorithm (mod 10) and validation digit, the digit to be appended to the digit sequence to make whole sequence checksum equal to zero.
Calculate check digit using the Luhn algorithm. Fill in the box below to have it instantly computed. The Luhn algorithm, a simple checksum verification algorithm, is also known as Luhn formula, modulus 10 algorithm, or mod 10 algorithm.
Tools to check Luhn generated numbers. The Luhn algorithm (also called modulo 10 or mod 10) is a checksum formula for numbers/digits used with credit card or administrative numbers.
The Luhn algorithm calculator uses two methods based on the same algorithm: Calculate the Luhn check digit for a given number; and Test a number for Luhn validation.
The Luhn Algorithm Calculator helps you determine whether a given card number is valid. This calculator is particularly useful for validating credit card numbers, debit card numbers, and other numerical identifiers.
Luhn algorithm has been developed to decrease probability of entering wrong identification numbers. The last digit is a checksum of the other digits. It is being used in credit card numbers, IMEI numbers, social security numbers, SIM card numbers and so on.
