Check Digit Verification of cas no
The CAS Registry Mumber 879999-66-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,9,9,9 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 879999-66:
(8*8)+(7*7)+(6*9)+(5*9)+(4*9)+(3*9)+(2*6)+(1*6)=293
293 % 10 = 3
So 879999-66-3 is a valid CAS Registry Number.

Synthesis of tetrahydrobenzazepinesulfonamides and their rearrangement to diarylsulfones
Ren, Hui,Zanger, Murray,McKee, James R.
, p. 355 - 363 (2006)
A new class of diarylsulfones, in which tetrahydrobenzazepine comprises one of the aromatic moieties, has been synthesized via the acid-catalyzed rearrangement of several substituted benzazepinesulfonamides. The rearrangement is normally ortho but in at l
