Champernowne's Constant

==Problem Statement==

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

<math>0.12345678910{\color{red}\mathbf 1}112131415161718192021\cdots</math>

It can be seen that the 12th digit of the fractional part is 1

If <math>d_n</math> represents the nth digit of the fractional part, find the value of the following expression.

<math>d_1 \times d_{10} \times d_{100} \times d_{1000} \times d_{10000} \times d_{100000} \times d_{1000000}</math>
