Check Digit Verification of cas no

The CAS Registry Mumber 134983-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,8 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134983-18:
(8*1)+(7*3)+(6*4)+(5*9)+(4*8)+(3*3)+(2*1)+(1*8)=149
149 % 10 = 9
So 134983-18-9 is a valid CAS Registry Number.

Aryltrifluoromethylative cyclization of unactivated alkenes by the use of PhICF3Cl under catalyst-free conditions

Guo, Jia,Xu, Cong,Liu, Xiaowei,Wang, Mang

, p. 2162 - 2168 (2019/02/27)

A concise and catalyst-free aryltrifluoromethylative cyclization of unactivated alkenes has been developed herein. The use of PhICF3Cl as a powerful trifluoromethylating agent allows easy transformations. A set of trifluoroethylated carbocycles and aza-hereocycles were efficiently synthesized in good yield and selectivity. A broad substrate scope, mild reaction conditions, and easy operation would make this method well-suited for applications.
