Based on the position of the each digit, every 2nd digit from the right-most payload are doubled, and each digit (or doubled) are summed up make up the total. The total is then modulated to create the checksum digit. The payload and the checksum digit make up the credit card number. To learn more about Luhn Algorithm, please refer Wikipedia page.
