A common method for calculating the check digits for credit cards is called the Luhn algorithm. Beginning with the second digit from the​ right, replace every other digit with its double. Then all of the digits in the newly calculated series are added in mod 10. The check digit is 10 minus this value.   Find the check digit for the given credit card number.   4563 2625 2104 353c
