Help with naming organic compounds

Hi, i've got c compound which is C9H8O, it's cyclooctatetraene but with an aldehyde sticking off the side i think, but i don't know how to name it? If anyone could give me an idea, or maybe i'm way off and there's no such thing as this compound! It's an 8Carbon ring with 4 alternating double bonds.
Please help, i'm really stuck.
Thanks.
