I suspect there are many interfaces that would reject this number, as it's not a visa, master card or amex (which start with a 4, 5 and 3 respectively).
5105105105105100 and 4111111111111111 might be better alternatives (other test numbers that also pass the luhn check).
And when using email addresses to test your software always use [something]@test.com instead of [whatevs]@example.com because the people at test.com love getting your random test data.
