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.
The digit sequence 72355 first appears in π at position 5,452 of the decimal expansion (the 5,452ordinal-suffix:nd digit after the integer 3).
