This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8 681 751 and was likely granted around 2014.

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
