Paint Number listings

sure, there are a ton of them

http://www.paint4models.com/

http://scalemodeldb.com/paint

www.cybermodeler.com/index.shtml  (see "color guides" at the top)

www.simmerspaintshop.com/page-RGB-colors-UK.html

and many more, some will list cross references from paint to paint, and FS to RAL, etc, etc

some are just color examples of the FS, BSC, RAL, with suggested paints next to them

but, for just quick look ups of "what color is H-56 in Model Master Acryls?", the http://www.paint4models.com/  page is easiest,,,,,,it includes more paint ranges than the often linked IPMS Stockholm charts include

I have 49 bookmarks in my "Colors" folder, and a lot of that conflicts,,,,so, if you need a different link, just ask

This one's handy too: http://www.acrylicosvallejo.com/en_US/media/0049261608364909a238add9b4a53745.cms/cc073-rev05.pdf

That Cybermodeler one is killer!

It is well to do a google search for such cross-reference charts, there are a number of them, as the above charts show, and each site has some advantages.

I like http://paintfinder.ehaltom.com. It seems to have a good database of color.
