Calculate Digit Verification of CAS Registry Number 712293-81:
(8*7)+(7*1)+(6*2)+(5*2)+(4*9)+(3*3)+(2*8)+(1*1)=147
147 % 10 = 7
So 712293-81-7 is a valid CAS Registry Number.

Copper-catalyzed one-pot synthesis of substituted benzimidazo[1,2-a] quinolines

Zhou, Bing-Wei,Gao, Jian-Rong,Jiang, Dong,Jia, Jian-Hong,Yang, Zhen-Ping,Jin, Hong-Wei

, p. 2794 - 2798 (2010)

A one-pot procedure for the synthesis of substituted benzimidazo[1,2-a] quinolines from the corresponding benzimidazoles and 2-bromobenzaldehydes has been developed. The titled products were prepared through Knoevenagel condensation and copper-catalyzed intramolecular Ullmann-type coupling in moderate to good yields. Georg Thieme Verlag Stuttgart.
