The fact in the hint is not necessary (but useful of course).
I missed it and found the same result by other reasons. Of course then I noticed the trick, but it was too late...
BTW, the hint is not completely correct, since there are two pairs of consecutive digits among the other four digits.
But one should try to change the puzzle by removing this possibility. I'll write you a PM, because otherwise it would give too much help to the readers.
