TYPE & SIZE

Owners code is expressed in equivalent values by prescribing a value of  10 to A, 12 to B, 13 to C and so up to 38 to Z.

(The values 11, 22 and 23 are excluded.)

EXAMPLE: ABZU   012345
                                   Then

                    A= 10 X 20
                    B= 12 X 21
                    Z= 38 X 22               

                    U= 32 X 23
                    0= 0 X 24               

                    1= 1 X 25
                    2= 2 X 26
                    3= 3 X 27
                    4= 4 X 28
                    5= 5 X 29
                  – – – – – – – – –
                    Total  4570

This total is then divided by 11 and the residue (in this case 5) is accepted as the check digit.
