Problem: An irrational decimal fraction is created by concatenating the positive integers:

`0.123456789101112131415161718192021...`

It can be seen that the 12^{th} digit of the fractional part is 1.

If d_{n} represents the n^{th} digit of the fractional part, find the value of the following expression.

d_{1} * d_{10} * d_{100} * d_{1000} * d_{10000} * d_{100000} * d_{1000000}
