Check Digit Verification of cas no

The CAS Registry Mumber 1620052-22-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,0,5 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1620052-22:
(9*1)+(8*6)+(7*2)+(6*0)+(5*0)+(4*5)+(3*2)+(2*2)+(1*2)=103
103 % 10 = 3
So 1620052-22-3 is a valid CAS Registry Number.

Palladium-catalyzed annulation of benzynes with N-substituted-N-(2- halophenyl)formamides: Synthesis of phenanthridinones

Yang, Yuan,Huang, Hui,Wu, Lijun,Liang, Yun

supporting information, p. 5351 - 5355 (2014/07/21)

A novel and efficient procedure for the synthesis of N-substituted phenanthridinones via palladium-catalyzed annulation of benzynes with N-substituted-N-(2-halophenyl)formamides has been developed. This methodology constructs two new C-C bonds via an arylation/annulation process, and provides the desired products in good yields. This journal is the Partner Organisations 2014.
