Ultegra cassette markings?

I just bought an e-bay item which was described as a new Ultegra 11-23
cassette. It came as loose cogs, carrier sections and spacers, but I
can't see any markings which would help me tell if it's really an
Ultegra or an off-brand, except for the lock ring which says "Shimano
HG CS-6500" and some other stuff. The two largest cogs are silver and
mounted on a carrier, and the rest are more of a bronze (brownish)
color. Each cog also has the number of teeth and "AK" stamped on
them. Are there any marks which should identify it as an Ultegra?

Thanks!

Shimano uses the 6500 series for Ultegra parts. CS-6500 is an Ultegra
cassette, FC-6500 is an Ultegra crank, etc. 7700 series is 9-speed DA
and 7800 series is 10-speed DA.

I figured that out, but are there supposed to be any of these markings
on the cogs themselves? The only part which has any ID is the lock
ring.

I looked at an Ultegra and a Dura Ace that I have and the only markings are
on the lock rings, except I can see an A1 and B1 on the inside clusters.
Both have the 3 largest cogs (A1) in a carrier and the next 2 (B2) in a
carrier. The rest are individual with spacers. The Ulltegra cogs are all
shiny silver. The Dura Ace cogs are dull and titanium colored. There's a
very obvious weight difference between the two, as there should be.

Thanks for the info! I figured out from the Shimano assembly manual
that which ones are on carriers depends on what sizes you are building.
For an 11-23, the two biggest are on one carrier, the next two on
another, and the rest of the cogs are individuals.
