Luhn Test fails for valid credit card numbers


Using both real card numbers and the publicly available test numbers, the CreditCard.IsValid method fails. Several published c# examples online also fail so this may explain the confusion. I found an example that works flawlessly. I've attached a subversion patch file that includes the change and a test to exercise both positive and negative test.
