EXAMPLE
| 603 is included because (1) none of its digits repeat, (2) the leftmost first digit is 6 which, divided by 1, yields an integer, (3) the sum of the leftmost 2 digits, i.e., 6+0=6, divided by 2 yields an integer, and (3) the sum of the leftmost 3 digits, i.e., 6+0+3=9, divided by 3 yields an integer.
