A number of 9 digits has the following properties:
• The number comprising the leftmost two digits is divisible by 2, that
comprising the leftmost three digits is divisible by 3, the leftmost four by 4,
the leftmost five by 5, and so on for the nine digits of the number i.e. the
number formed from the first n digits is divisible by n, 2<=n<=9.
• Each digit in the number is different i.e. no digits are repeated.
• The digit 0 does not occur in the number i.e. it is comprised only of the
digits 1-9 in some order.
Find the number.
