What chain for Shimano RSX chainset?

The chain needs replacing on my bike, which is equipped with a 21 speed Shimano RSX chainset. I don't recognise any of the markings on the original chain as being similar to anything currently available online. In a hurry I bought a Shimano HG70 chain as a replacement, because it is quoted as being suitable for 6/7/8 speed cassettes. I just wondered if there is anything which is better suited for the job.

Any chain that is for 7sp will do the job. The one you have is as good as any.
