Check Digit Verification of cas no

The CAS Registry Mumber 70590-11-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,9 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 70590-11:
(7*7)+(6*0)+(5*5)+(4*9)+(3*0)+(2*1)+(1*1)=113
113 % 10 = 3
So 70590-11-3 is a valid CAS Registry Number.

CF3SO2Na as a Bifunctional Reagent: Electrochemical Trifluoromethylation of Alkenes Accompanied by SO2 Insertion to Access Trifluoromethylated Cyclic N-Sulfonylimines

He, Zeying,Jiao, Lingcong,Li, Zheng,Liao, Wei-Wei,Sun, Yunhai,Wei, Zhonglin

supporting information, p. 7266 - 7270 (2020/03/23)

An unprecedented electrochemical trifluoromethylation/SO2 insertion/cyclization process has been achieved in an undivided cell in an atom-economic fashion. The protocol relies on tandem cyclization of N-cyanamide alkenes by using Langlois’ reagent as a source of both CF3 and SO2 under direct anodically oxidative conditions, in which two C?C bonds, two C?X bonds (N?S and S?C), and two rings were formed in a single operation. This transformation enabled efficient construction of various trifluoromethylated cyclic N-sulfonylimines from readily accessible materials.
