Cipher- Back to the Number Puzzles

Find the cipher if:

1. The cipher is made of 6 different numerals.

2. Even and odd figures alternate, including zero (in this case as an even number).

3. The difference of adjacent numerals is always bigger than one.

4. The first two numerals (as one number) as well as the two middle numerals (as one number) are a multiple of the last two numerals (as one number).

I'm not seeing how the first two and second two numerals are a multiple of the last two numerals in 496307. Can you help me out?
