574-68-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 574-68-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,7 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 574-68:
(5*5)+(4*7)+(3*4)+(2*6)+(1*8)=85
85 % 10 = 5
So 574-68-5 is a valid CAS Registry Number.

Halogenation of 1,1-diarylethylenes by N-halosuccinimides

Zhang, Ge,Bai, Rui-Xue,Li, Chu-Han,Feng, Chen-Guo,Lin, Guo-Qiang

, p. 1658 - 1662 (2018/12/11)

An efficient method for the preparation of 2,2-diarylvinyl halides from the corresponding 1,1-diarylethylenes has been developed. N-Halosuccinimides (N-bromosuccinimide or N-chlorosuccinimide) were used as the halogenation reagents. The practicability of this method is highlighted by its simple operation, broad substrate scope and capability for large-scale reaction.
