Check Digit Verification of cas no

The CAS Registry Mumber 92646-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,6,4 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 92646-08:
(7*9)+(6*2)+(5*6)+(4*4)+(3*6)+(2*0)+(1*8)=147
147 % 10 = 7
So 92646-08-7 is a valid CAS Registry Number.

Carbon annulation of ortho-vinylanilines with dimethyl sulfoxide to access 4-aryl quinolines

Yuan, Jin,Yu, Jin-Tao,Jiang, Yan,Cheng, Jiang

, p. 1334 - 1337 (2017)

A palladium-catalyzed annulation of ortho-vinylanilines with dimethyl sulfoxide was developed to access 4-aryl quinolines in moderate to good yields. Activated by 1,4-diazabicyclo[2.2.2]octane bis(sulfur dioxide) adduct (DABSO), DMSO served as a “=CH-” fragment in this transformation. It represents a facile pathway leading to 4-aryl quinolines.

Copper-mediated intramolecular aza-Wacker-type cyclization of 2-alkenylanilines toward 3-aryl indoles

Yang, Rui,Yu, Jin-Tao,Sun, Song,Zheng, Qingheng,Cheng, Jiang

supporting information, p. 445 - 448 (2017/01/11)

A copper-mediated intramolecular aza-Wacker-type cyclization was developed for the direct and efficient synthesis of 3-aryl indoles using 2-alkenylanilines in moderate to good yields with good functional group compatibility. This strategy shows the high efficiency, operational simplicity as well as broad substrate scope.

Intramolecular addition of triarylmethanes to alkynes promoted by KOtBu/DMF: A synthetic approach to indene derivatives

Chen, Yan-Yan,Chen, Zhen-Yu,Zhang, Niu-Niu,Chen, Jia-Hua,Zhang, Xue-Jing,Yan, Ming

, p. 599 - 606 (2016/02/19)

A method for the intramolecular addition of triarylmethanes to alkynes has been developed. The reaction was efficiently promoted by KOtBu/DMF without any transition-metal catalyst. A variety of indene derivatives were prepared in moderate to good yields. A cascade cyclization of 2-alkyl-substituted substrates at elevated reaction temperature gave bicyclic indene derivatives. The reaction is proposed to proceed through the generation of a triphenylmethyl radical. Indene derivatives were prepared by the intramolecular addition of triarylmethanes to alkynes promoted by KOtBu/DMF. A cascade cyclization of 2-alkyl-substituted substrates at elevated reaction temperature gave bicyclic indene derivatives. A free-radical reaction mechanism is proposed.
