There is one unique 10 digits number that has the following:

All digits are according to their position as follows:

0|1|2|3|4|5|6|7|8|9

So, the first digit from left (0) will have one number (from 0 to 9 of course) This number corresponds to the number of 0s that the whole number has. If for example it has 4 zeros the first digit must be 4.

The second digit (1) will have the number of 1s that the number has

The third digit (2) will have the number of 2s that the number has

The fourth digit (3) will have the number of 3s that the number has

and so on...

This number is unique. What is the number?
