Check Digit Verification of cas no

The CAS Registry Mumber 78195-97-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,9 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 78195-97:
(7*7)+(6*8)+(5*1)+(4*9)+(3*5)+(2*9)+(1*7)=178
178 % 10 = 8
So 78195-97-8 is a valid CAS Registry Number.

Terminal Trifluoromethylation of Ketones via Selective C-C Cleavage of Cycloalkanols Enabled by Hypervalent Iodine Reagents

Wu, Shuang,Li, Junzhao,He, Ru,Jia, Kunfang,Chen, Yiyun

supporting information, p. 9204 - 9209 (2021/11/30)

We report the first terminal trifluoromethylation at aryl and alkyl ketones' ?, or more remote sites via the selective C-C bond cleavage of cycloalkanols. The noncovalent interactions between alcohols and hypervalent iodines(III) reagents were disclosed to activate both alcohols and the Togni I reagent in the dual photoredox/copper catalysis for the transformation. This reaction was scalable to the gram-scale synthesis, applicable to the structurally complex steroid trifluoromethylation, and extendable to the pentafluoroethylation.

New therapeutically active basic ethers. 1. 1-Arylcycloalkanol derivatives.
