Now....take a look at 14 CFR 121.547......

"§ 121.547 Admission to flight deck.
(a) No person may admit any person to the flight deck of an aircraft unless the person being admitted is—
(1) A crewmember;"

The remaining sections of 14 CFR 121 deal with admitting certain officials of the United States Gov't into the flight deck.

I don't dispute that jumpseating occurs prior to becoming a qualified crewmember. I suppose most Captains assume that you have passed the SIC ride......or maybe they aren't familiar with the regs.

CASS doesn't necessarily admit you to the jumpseat. It is a visual verification tool used prior to allowing admittance. What allows admittance is having the proper credentials to be a crewmember.
