Bank ING has a serie of bankaccounts that does not follow your algoritm. Those are the former 'Postbank' accounts.
Is there a way to check those too?

for Postbank numbers there is no validity check. The only thing you could do with those is that the numeric value must be less than 100.000.000 (100 million).

Only ING (Postbank) can check if it is a valid, issued number..
