IbanNet does not support BBAN check digit validation out of the box, only IBAN check digits. There is an extension package (IbanNet.Extensions.Bban) in the works for this but especially German bank account numbers are problematic because there are tons of variations (by different banks/regions). There is currently no support for it yet.

Please create an feature request or contribute in that repo.
