I'm having really hard time to get a regular expression for the following cards / scenarios:

Maestro:

Valid:
5759877498192
67309415708416
6641120953323
633047943612610
50367590462448
509705198158

Not valid:
6369634818975813
66103205252298716302
6526725494191975280
67098365838600780
630453133428820927

regex: ^(6|50|56|57|58|503)(?!36)\d{11,18}$

Discover Card:

Valid:
6222117726251007070
6532550590530780378
6473780297817696280
6221567796889380121
6585471921818715
6223510391605033

Not valid:
62268883925361333717
64795258022225006
6004952515759546352

regex: ^6(011|5|22(12[6-9]|1[3-9][0-9]|[2-8][0-9]{2}|9[01][0-9]|92[0-5])|4[4-9])[0-9]+$

As you can see the reg exp I'm using fails in some scenarios.

I'm using the following url as reference https://en.wikipedia.org/wiki/Payment_card_number

Can you list out the rules for credit card validation? – Aron Mar 27 '17 at 17:12
@Aron What do you mean? I'm using the rules according the wiki page for all cards. – user2019037 Mar 27 '17 at 17:14
Maybe this would be useful? http://stackoverflow.com/a/23231321/4333555 – chris85 Mar 27 '17 at 17:14
@chris85 doesn't work for me for those cases :/ – user2019037 Mar 27 '17 at 17:15
@anubhava Because is Laser prefix not maestro :/ – user2019037 Mar 27 '17 at 17:16
I'm most interest on a maestro solution. – user2019037 Mar 27 '17 at 17:40
@anubhava Do you mean to post my other reg exp too and the other test cases? – user2019037 Mar 27 '17 at 17:45
How is `6526725494191975280` an invalid Maestro card number? – Thomas Ayoub Mar 28 '17 at 08:49
