Umm... maybe I'm off my game (I am home sick after all) but don't that doesn't sound like an actual chemical.
Ethane has room for 6 substituants, and you've got seven listed (5 chloros and 2 phenyls) unless I'm misreading.

And the 2,2-dichloros can be on the phenyls (one substituant on each carbon).
