Euler Problem: Pandigital number

Multiplying 9 by 1, 2, 3, 4, and 5, gives the pandigital, 918273645, which is the concatenated product of 9 and (1,2,3,4,5).

What is the largest 1 to 9 pandigital 9-digit number that can be formed as the concatenated product of an integer with (1,2, ... , n) where n >1?

Its fun to solve the problem without the use of code :)
