012 Is the right

And for those few who disagree, here's the way to the solution:
The 4th hint tells us that there is no 3, 7, 8 in the number.
With 7 and 8 ruled out, the 5th hint tells us that 0 is a correct number, but not the last digit.
The 3rd hint tells us that 0 must be first digit then and the number either 06x, 02x or 0x2.
With 0 as the first digit and 8 ruled out, 2 must be last digit according to the 1st hint, so 0x2.
The 2nd hint leads to the 4 as the correct digit in a wrong spot, so the solution is "042".
