Invalid 17 and 18 digit Visa Card Numbers passing validation successfully which is wrong

[MartinAleksandrovLT]

Based on https://en.wikipedia.org/wiki/Payment_card_number Visa card numbers can only be 13, 16 and 19 digits long.

Currently 17 and 18 digit Visa card numbers pass validation successfully but they are supposed to fail

In case it helps discussion, below that table there is the following snippet:

"While the vast majority of Visa's account ranges describe 16 digit card numbers there are still a few account ranges (forty as of 11 December 2013) dedicated to 13 digit PANs and several (439 as of 11 December2013) account ranges where the issuer can mix 13 and 16 digit card numbers. Visa's VPay brand can specify PAN lengths from 13 to 19 digits and so card numbers of more than 16 digits are now being seen."

Not sure if that has an effect on the inclusion of other digit lengths or not.
