Dee finds that she has an extraordinary social security number. Its nine digits contain all the digits from 1 to 9. They also form a number with the following characteristics:

  1. When read from left to right the first two digits form a number divisible by two.
  2. The first three digits form a number divisible by three.
  3. The first four digits a number divisible by four, and so on, until the complete number is divisible by 9.

What is Dee's social security number?
