Check Digit Verification of cas no

The CAS Registry Mumber 1227188-09-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,1,8 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1227188-09:
(9*1)+(8*2)+(7*2)+(6*7)+(5*1)+(4*8)+(3*8)+(2*0)+(1*9)=151
151 % 10 = 1
So 1227188-09-1 is a valid CAS Registry Number.

Palladium-catalyzed synthesis of carbazoles from N-(2-halophenyl)-2,6-diisopropylanilines via C-C cleavage

Chianese, Anthony R.,Rogers, Scott L.,Al-Gattas, Hanna

supporting information; experimental part, p. 2241 - 2243 (2010/05/18)

The synthesis of 1-isopropyl-substituted carbazoles by the palladium-catalyzed dealkylative cyclization of N-(2-halophenyl)-2,6-diisopropylanilines is described. The reaction involves intramolecular C-C bond formation, coupled with the cleavage of a C-X bond and a C-C bond, and is proposed to proceed through the formation of a dearomatized intermediate.
