The hundreds digit in the given expression is the same as the tens digit in the expression $5\times 6\times 7\times 8\times 9$, which is the same as the ones digit in the expression $6\times 7\times 4\times 9$ (we divide out a 10 each time). $6\times 7=42$ has a ones digit of 2 and $4\times 9=36$ has a ones digit of 6, and $2\times 6=12$, so the entire product has a ones digit of $\boxed{2}$.
