Check Digit Verification of cas no
The CAS Registry Mumber 665033-21-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,5,0,3 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 665033-21:
(8*6)+(7*6)+(6*5)+(5*0)+(4*3)+(3*3)+(2*2)+(1*1)=146
146 % 10 = 6
So 665033-21-6 is a valid CAS Registry Number.

Synthesis of benzannelated sultams by intramolecular Pd-catalyzed arylation of tertiary sulfonamides
Rassadin, Valentin A.,Scholz, Mirko,Klochkova, Anastasiia A.,De Meijere, Armin,Sokolov, Victor V.
supporting information, p. 1932 - 1939 (2017/09/27)
A new and efficient approach to five- and six-membered benzannelated sultams by intramolecular C-arylation of tertiary 1-(methoxycarbonyl)methanesulfonamides under palladium catalysis is described. In case of the α-toluenesulfonamide derivative, an unexpected formation of a 2,3-diarylindole was observed under the same conditions.
