I didn't think 0 counted.

Here's a problem from a competition i just did:
abcd is a 4 digit number between 1000 and 9999. When you multiply a 3 digit number (efg) and a 2 digit number (hi) and a 1 digit number (j) you get abcd. a,b,c,d,e,f,g,h,i, and j use the numbers 0-9 once and only once. What are the two combinations that work?
abcd=efg*hi*j
