Accidently I cleaned my new Nikon NC filter
by "Glass Cleaner:Formula 409"
Did I damage it?
Thank you for any respond and advice.

No, you should be OK, unless you see any signs that the coating has been rubbed off. 409 is a de-greasant that's a bit aggressive for optical use, but using it once shouldn't hurt. I use the gentler amonium-based Windex on filters and lenses, no problem!
However, never spray any product directly on to the lens - it might seep in past the edges and damage go where it's not supposed to. Always spray onto a soft cleaning cloth, never the surface!

Sorry, you have not received a post for this request.
I've been assigned the moderator for this forum and hope to prevent this from happening in the future.
I don't believe you have damaged the filter. However, I would suggest you wash it in warm water gently rubbing the glass with dishwashing soap. I keep a small bottle of Dawn under the sink just to wash filters and other photo gear.
Also, you might be interested in my posting under "Filters as lens protectors" in this same forum.
Hope this helps...
