Credit Card Checksum Verification

This is a CLASSIC ASP project.

I need some ASP written for me which will verify the checksum of a credit card number in order to know that the number is valid.

I will be passing the credit card number to the script via a form using POST.

The credit cards I will be passing will be Diners, Amex, Visa, Mastercard, Switch and Visa Electron.

I have been reading around and can see that usually this is done using the LUHN formula but I am not sure if its an outdated method, I need the latest way of doing this but in CLASSIC ASP.
