928712-61-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 928712-61-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,7,1 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 928712-61:
(8*9)+(7*2)+(6*8)+(5*7)+(4*1)+(3*2)+(2*6)+(1*1)=192
192 % 10 = 2
So 928712-61-2 is a valid CAS Registry Number.

Synthesis of Chiral Triarylmethanes Bearing All-Carbon Quaternary Stereocenters: Catalytic Asymmetric Oxidative Cross-Coupling of 2,2-Diarylacetonitriles and (Hetero)arenes

Wang, Zehua,Zhu, Yasheng,Pan, Xiaoguang,Wang, Gang,Liu, Lei

, p. 3053 - 3057 (2020)

A direct and enantioselective oxidative cross-coupling of racemic 2,2-diarylacetonitriles with electron-rich (hetero)arenes has been described, which allows for efficient construction of triarylmethanes bearing all-carbon quaternary stereocenters with excellent chemo- and enantioselectivity. The reaction has an excellent functional group tolerance, and exhibits a broad scope with respect to both 2,2-diarylacetonitrile and (hetero)arene components. The rich chemistry of the cyano group allows for facile synthesis of other valuable chiral triarylmethanes bearing all-carbon quaternary centers that are otherwise difficult to access.
