Check Digit Verification of cas no

The CAS Registry Mumber 1581695-43-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,1,6,9 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1581695-43:
(9*1)+(8*5)+(7*8)+(6*1)+(5*6)+(4*9)+(3*5)+(2*4)+(1*3)=203
203 % 10 = 3
So 1581695-43-3 is a valid CAS Registry Number.

Copper-Catalyzed C-H Stereoselective Cyanation of Alkenes by Using an α-Iminonitrile as a Cyanating Reagent

Chen, Zhen-Bang,Gao, Qing-Qing,Liu, Kui,Zhu, Yong-Ming

supporting information, p. 203 - 206 (2019/01/14)

The first copper-catalyzed cyanation through alkene C-H bond activation by using an α-iminonitrile as a cyanating agent has been realized. The approach efficiently constructs acrylonitriles in good yields with the advantages of high regioselectivity, cost

Efficient preparation of o-cyanation aromatic ring or unsaturated fat ring compound by transition-metal catalyzed C-H coupling reaction

-

Paragraph 0019; 0020, (2018/11/04)

The invention relates to a novel green synthesis method for efficiently preparing an o-cyanation aromatic ring or unsaturated fat ring compound on the basis of a transition-metal catalyzed C-H coupling reaction using N1,N3-di-substituted imidazole ionic l

Rhodium-catalyzed direct C-H bond cyanation of arenes with isocyanide

Hong, Xiaohu,Wang, Hao,Qian, Guangyin,Tan, Qitao,Xu, Bin

, p. 3228 - 3237 (2014/05/06)

An efficient rhodium-catalyzed regioselective C-H bond cyanation of arenes was developed using tert-butyl isocyanide as the cyanide source. A wide range of (hetero)aryl and cycloalkenyl nitriles could be afforded with high regioselectivity and good functional group tolerance.
