Implementei essa função em typescript e testei os cartões que o @MMortari mandou, alguns falharam:

Comlementando, os cartões que deram errado passam na REGEX da bandeira esperada, mas também passam na da Discover/Aura. Eu comentei essas duas bandeiras e a maioria passou, só o 5031433215406351 que não está passando na REGEX do mastercard

Interessante esse comportamento, vou fazer alguns testes aqui e quem sabe com um negative lookahead ele funcione corretamente, posteriormente comentarei com um retorno ...
