Implement the Luhn algorithm, by taking each digit of a number, from right to left, and doubling every other digit starting with the second digit from the right. If doubling a digit results in a number greater than 9, then the digits of that number are summed together (or equivalently, 9 is subtracted from the result). After this process, all the digits (those doubled and those not) are summed together. If the total sum is a multiple of 10, the number is considered to be valid.
