    Method of Calculating Chequesum

    The cheque digit is the routing number's ninth digit and must meet the following criteria.

    3(d1 + d4 + d7) + 7(d2 + d5 + d8) + (d3 + d6 + d9) mod 10 = 0
    (Mod or modulo is the remainder of a division operation.)

    As an example, the routing number of Bank Of America, Virginia is 011900571. So, according to the chequesum calculation method -

    0

    100 mod 10 = 0
