You'd need to build him more for sustained damage than burst damage that way, so he could survive long enough to make that work. Technically he does have the highest naked DPS of all champions in the game at level 18, and his magic damage on hit active and attack speed passive can bring him to melee ADC damage levels in terms of damage output. The only problem with that is melee ADCs are outclassed by things like burst assassins and ranged carries in most cases, the former of which Kassadin can also do rather well. Overall I'd imagine he has the stats to pull it off, but there's probably better items for him. If you have 600 AP you're probably infinity better off picking up survivability as well.
I'd probably check the Dominion forums for Kassadin builds though, he's pretty popular (and overpowered) there, so you'd probably have the best luck finding effective builds within those forums.
