The star mentioned in the book is identified as "NGS 549672"; if I'm not
mistaken, "NGS" refers to a particular star catalog (National Galactic
Survey?) and "549672" uniquely identifies a specific star.

I work with astronomical catalogs a lot and I'm sorry to say that there
doesn't seem to be any NGS catalog. The number is also way too big for
a catalog from the 50's (remember that's the pre-computer era), so I
think it's safe to say that it was simply made up. You are right about
how it would work though.

Some links if you are still curious:
SIMBAD http://simbad.u-strasbg.fr/
NED http://nedwww.ipac.caltech.edu/

Really? The novel, Childhood's End, is by Arthur C. Clarke. I always thought
Clarke had a reputation as a genuine scientist, not just a novelist. I had
expected accuracy from him.

In 1953, looking up something like that catalog number would probably have
been something you could only do at a major metropolitan library or
university with an astrophysics department. I assumed this reference was
basically an inside joke for the readers he had who were actually
astronomers....

Well, I guess I was wrong and the reference is bogus.

Thank you for clearing that up! Your note probably also explains why my
google search on the NGS number failed to work.
