Check Digit Verification of cas no

The CAS Registry Mumber 1616392-39-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,3,9 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1616392-39:
(9*1)+(8*6)+(7*1)+(6*6)+(5*3)+(4*9)+(3*2)+(2*3)+(1*9)=172
172 % 10 = 2
So 1616392-39-2 is a valid CAS Registry Number.

Cerium(iii)-catalyzed cascade cyclization: An efficient approach to functionalized pyrrolo[1,2-a]quinolines

Feng, Chengtao,Yan, Yizhe,Zhang, Zhenglei,Xu, Kun,Wang, Zhiyong

supporting information, p. 4837 - 4840 (2014/07/07)

A general and practical route to the synthesis of multisubstituted pyrrolo[1,2-a]quinolines has been described from 2-alkylazaarenes and nitroolefins using cerium chloride as a catalyst via a tandem Michael addition, cyclization and aromatization. This protocol features readily available starting materials, operational simplicity and high regioselectivity to access multifunctionalized pyrrolo[1,2-a]quinolines with the formation of multiple C-C and C-N bonds in one pot. In addition, various substitution patterns and functional groups were found to be compatible under the optimized conditions, which was lacking in the existing procedures. This journal is the Partner Organisations 2014.
