Check Digit Verification of cas no

The CAS Registry Mumber 121513-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,1 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121513-89:
(8*1)+(7*2)+(6*1)+(5*5)+(4*1)+(3*3)+(2*8)+(1*9)=91
91 % 10 = 1
So 121513-89-1 is a valid CAS Registry Number.

Nickel-catalyzed Kumada Cross-coupling Reaction for the Synthesis of 2,4-Diarylquinazolines

Ye, Xinglin,Yuan, Zhihan,Zhou, Yirong,Yang, Qin,Xie, Yepeng,Deng, Zhihong,Peng, Yiyuan

, p. 1956 - 1962 (2016)

A series of 2,4-diarylquinazolines have been successfully synthesized via the Ni-catalyzed cross-coupling reaction of quinazoline-4-tosylates and aryl Grignard reagents, which provided alternative straightforward approaches for the introduction of aryl groups to quinazolines at C-4 position.

Synthesis of 4-arylquinazolines by arylation of quinazolin-4-ones under mild conditions

Qiu, Guanyinsheng,Huang, Ping,Yang, Qin,Lu, Hui,Xu, Jingshi,Deng, Zhihong,Zhang, Ming,Peng, Yiyuan

supporting information, p. 3131 - 3136 (2013/12/04)

An efficient route to 4-arylquinazolines via arylation of quinazolin-4-ones under mild condition is described. The reaction is carried out by the palladium-catalyzed coupling of quinazolin-4-ones with arylboronic acids in the presence of TsCl leading to 4-arylquinazolines in good to excellent yields.
