This number must pass the following test: From the rightmost digit, which is the check digit, moving left, double the value of every second digit; if the product of this doubling operation is greater than 9 (e.g., 8 × 2 = 16), then sum the digits of the products (e.g., 16: 1 + 6 = 7, 18: 1 + 8 = 9) or alternatively subtract 9 from the product (e.g., 16: 16 - 9 = 7, 18: 18 - 9 = 9). Take the sum of all the digits. If the total modulo 10 is equal to 0 (if the total ends in zero) then the number is valid according to the Luhn formula; else it is not valid. Assume an example of an account number "7992739871" that will have a check digit added, making it of the form 7992739871x: Account number 7 9 9 2 7 3 9 8 7 1 x Double every other 7 18 9 4 7 6 9 16 7 2 x Sum digits 7 9 9 4 7 6 9 7 7 2 x The sum of all the digits in the third row is 67+x. The check digit (x) is obtained by computing the sum of the non-check digits then computin
