9 Speed chain rubs on 9 Speed cassette

I have a 9 speed Shimano cassette and I just put a SRAM PC 1090 chain on. The chain seems to rub against the cassette cogs in all gears. There is resistance as I pedal it slowly by hand and the resistance occurs with every chain pin. Derailleur and hanger are straight. Chain line looks good. How can this chain be too wide?

A good measurement beats 1000 expert opinions.

Can you measure outer width of the chain and sprocket pitch (middle to middle)?

Is the RD cable set up properly - so it isn't too tight, nor too loose?

Maybe it is an 8/7/6/5 speed chain that was misboxed. Roger

The SRAM PC 1090 is sold as a 10 speed chain

Duh. I had the chain misthreaded through the rear derailleur. Fixed that and it is smooth now. I have a head injury so that's my excuse and I'm sticking with it. Thank you for the help.
