100191-80-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 100191-80-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,1,9 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 100191-80:
(8*1)+(7*0)+(6*0)+(5*1)+(4*9)+(3*1)+(2*8)+(1*0)=68
68 % 10 = 8
So 100191-80-8 is a valid CAS Registry Number.

Efficient method for the synthesis of chiral pyrrolidine derivatives via ring-closing enyne metathesis reaction

Yang, Qian,Alper, Howard,Xiao, Wen-Jing

, p. 769 - 771 (2007)

(Chemical Equation Presented) A series of new pyrrolidine derivatives were prepared directly in very good yields, from the substrates containing a basic or nucleophilic N atom via ring-closing enyne metathesis reaction under mild reaction conditions. More

Zinc(ii)-catalyzed intramolecular hydroarylation-redox cross-dehydrogenative coupling of N -propargylanilines with diverse carbon pronucleophiles: Facile access to functionalized tetrahydroquinolines

Li, Guangzhe,Wang, Chengdong,Li, Yueqing,Shao, Kun,Yu, Guo,Wang, Shisheng,Guo, Xiuhan,Zhao, Weijie,Nakamura, Hiroyuki

, p. 7333 - 7336 (2020/07/23)

Zinc(ii)-catalyzed intramolecular hydroarylation-redox cross-dehydrogenative coupling of N-propargylanilines with two types of carbon pronucleophiles (nitromethane as a sp3 carbon pronucleophile and phenylacetylenes as sp carbon pronucleophiles) proceeded to give the 2-substituted tetrahydroquinolines in good yields with 100percent atomic utilization without any additional external oxidants.

Synthesis of substituted 3-indolylimines and indole-3-carboxaldehydes by rhodium(II)-catalyzed annulation

Rajagopal, Basker,Chou, Chih-Hung,Chung, Ching-Cheng,Lin, Po-Chiao

, p. 3752 - 3755 (2014/08/05)

An efficient Cu/Rh-catalyzed method is proposed for the synthesis of 3-indolylimines from N-propargylanilines through Rh(II)-catalyzed denitrogenative annulation of N-sulfonyl-1,2,3-triazoles. Further combined with hydrolysis or reduction, a one-pot method is developed to enable the direct incorporation of an imine, aldehyde, or amine group into an indole system from an alkyne. A variety of substituted 3-indolylimines, indole-3-carboxaldehydes, and 3-Indolylmethanamines are synthesized in good yields.
