Brainteaser time!!!

OK, so in my INTD we had a really cool brainteaser math challenge thing. I now present it to you all.

You have the numbers 0,1,2,3,4,5,6,7,8,9 so there are 10
now you have 10 lines for a 10 digit number.
_ _ _ _ _ _ _ _ _ _

The task is to rearrange the 10 digits it make a 10 digit number.
The condition is the first 2 must be divisible by 2, the first 3 by 3, etc. By this I mean something like the number 123. 12 is divisible by 2 and 123 is divisible by 3.

This took me a while to figure out, but I was the only person who did so in my class. See if you can do it! or don't... that's good too. I'm gonna put my answer behind the cut. Maybe you can get something different.


I got:
3816547290

drop me a line if you get this or another answer!!


On another note, it's really windy and I was feeling feverish earlier. But all is well. I have anime club tonight. yay!!
