Luhn Algorithm Check Credit Card

The Luhn algorithm is based on a formula that validates a variety of credit card numbers. The Luhn algorithm was settled in August 1960, and it’s widely used in the validation of credit cards. This algorithm is utilized by people for identifying mistyping or incorrect entries of card numbers in the banking and government sectors. If you have come across a card and want to check whether it’s valid or not, then you must run it through the Luhn algorithm to check. The credit card number that passes the Luhn algorithm check will indicate that it’s a valid card.

How does the Luhn Algorithm Validate Credit Card Number?

The formula used by Luhn Algorithm for validating a credit card number is discussed in the steps below.

• First of all, remove the last digit from the credit card number you want to check.
• Secondly, reverse all the digits.
• Then multiply the odd digits in the number by two.
• Subtract the digits higher than 9 from 9.
• Add all digits.
• Take mode 10 on the sum of digits.
• If the answer is the same as the last digit of the card, then the card number is valid as per the Luhn algorithm.
