Check Digit Verification of cas no

The CAS Registry Mumber 1287736-93-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,7,7,3 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1287736-93:
(9*1)+(8*2)+(7*8)+(6*7)+(5*7)+(4*3)+(3*6)+(2*9)+(1*3)=209
209 % 10 = 9
So 1287736-93-9 is a valid CAS Registry Number.

Oxidative Trimerization of Amino Acids: Selective Synthesis of 2,3,5-Trisubstituted Pyridines

Xiang, Jia-Chen,Cheng, Yan,Wang, Zi-Xuan,Ma, Jin-Tian,Wang, Miao,Tang, Bo-Cheng,Wu, Yan-Dong,Wu, An-Xin

supporting information, p. 2997 - 3000 (2017/06/07)

An oxidative trimerization of three amino acids has been realized to furnish 2,3,5-trisubstuitued pyridines in both cross- and homo-trimerization types. This method is capable of converting simple linear biomass material to heterocycles, which features in

Synthesis of Polysubstituted Imidazoles and Pyridines via Samarium(III) Triflate-Catalyzed [2+2+1] and [4+2] Annulations of Unactivated Aromatic Alkenes with Azides

Wang, Yingchun,Li, Jiuling,He, Yan,Xie, Yuyang,Wang, Hengshan,Pan, Yingming

, p. 3229 - 3241 (2015/11/03)

Samarium(III) triflate-catalyzed [2+2+1] and [4+2] annulations have been identified for the preparation of fully substituted imidazoles and 2,3,5-trisubstituted pyridines from the readily available unactivated aromatic alkenes and azidomethyl aromatics. T

A metal-free decarboxylative cyclization from natural α-amino acids to construct pyridine derivatives

Wang, Qiang,Wan, Changfeng,Gu, Yang,Zhang, Jintang,Gao, Lingfeng,Wang, Zhiyong

supporting information; experimental part, p. 578 - 581 (2011/05/06)

A metal-free decarboxylative cyclization from natural α-amino acids was developed and applied in the preparation of pyridine derivatives. By virtue of this method, a series of pyridines containing the moiety of natural α-amino acids can be synthesized efficiently from the corresponding natural α-amino acids.
