You can validate a card number on your own too. Double every other number, starting with the first number. Add the result of those multiplications to all of the other digits on the card, treating all numbers as individual digits, including double digit results from the doubling operation. If the sum of all these numbers is divisible by ten, the number is valid according to the ISO standard. However, a valid card number doesn’t necessarily mean the number is an active account or that charges can be made with it.
