Check Digit Verification of cas no

The CAS Registry Mumber 1362191-54-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,6,2,1,9 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1362191-54:
(9*1)+(8*3)+(7*6)+(6*2)+(5*1)+(4*9)+(3*1)+(2*5)+(1*4)=145
145 % 10 = 5
So 1362191-54-5 is a valid CAS Registry Number.

Copper-catalyzed one-pot synthesis of imidazo/benzoimidazoquinazolinones by sequential ullmann-type coupling and intramolecular C - H amidation

Xu, Hao,Fu, Hua

supporting information; experimental part, p. 1180 - 1186 (2012/03/08)

A simple, practical, and highly efficient copper-catalyzed one-pot synthesis of imidazo/benzoimidazoquinazolinones has been developed. The procedure is based on a sequential copper-catalyzed Ullmann-type N-arylation and aerobic oxidative intramolecular C - H amidation. This method should provide a new and useful strategy for construction of N-heterocycles. A simple, practical, and highly efficient copper-catalyzed one-pot synthesis of imidazo/ benzoimidazoquinazolinones based on a sequential Ullmann-type N-arylation and aerobic oxidative intramolecular C - H amidation has been developed (see scheme).
