Check Digit Verification of cas no

The CAS Registry Mumber 1286729-10-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,7,2 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1286729-10:
(9*1)+(8*2)+(7*8)+(6*6)+(5*7)+(4*2)+(3*9)+(2*1)+(1*0)=189
189 % 10 = 9
So 1286729-10-9 is a valid CAS Registry Number.

One-Pot Synthesis of Benzene and Pyridine Derivatives via Copper-Catalyzed Coupling Reactions

Han, Jianwei,Guo, Xin,Liu, Yafeng,Fu, Yajie,Yan, Rulong,Chen, Baohua

supporting information, p. 2676 - 2681 (2017/08/16)

A highly efficient one-pot synthesis of polysubstituted pyridine has been achieved through copper-catalyzed oxidative sp3 C?H coupling of acetophenones with toluene derivatives. Besides, the polysubstituted benzene was obtained through copper-catalyzed coupling of acetophenones. Both of the reactions exhibited a good functional group tolerance to produce a 2,4,6-triphenylpyridine or 1,3,5-triarylbenzene in high yields. Compared with previous methods, these transformations allow a highly flexible and efficient preparation of substituted pyridines and benzenes. (Figure presented.).

Synthesis of Polyfunctional Pyridines via Copper-Catalyzed Oxidative Coupling Reactions

Fu, Yajie,Wang, Panpan,Guo, Xin,Wu, Ping,Meng, Xu,Chen, Baohua

, p. 11671 - 11677 (2016/12/09)

An efficient and concise approach for the synthesis of polysubstituted pyridines has been achieved through copper-catalyzed oxidative sp3 C-H coupling of oxime acetates with toluene derivatives. Besides, benzylamine and p-toluenesulfonylhydrazo

Copper-Catalyzed coupling of oxime acetates with aldehydes: A new strategy for synthesis of pyridines

Ren, Zhi-Hui,Zhang, Zhi-Yuan,Yang, Bing-Qin,Wang, Yao-Yu,Guan, Zheng-Hui

supporting information; experimental part, p. 5394 - 5397 (2011/12/02)

Copper-catalyzed coupling of oxime acetates with aldehydes offers a new strategy for the synthesis of highly substituted pyridines. This novel method tolerates a wide range of functionality and allows for rapid elaboration of the oxime acetates into a variety of substituted pyridines.
