Check Digit Verification of cas no

The CAS Registry Mumber 1023937-37-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,9,3 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1023937-37:
(9*1)+(8*0)+(7*2)+(6*3)+(5*9)+(4*3)+(3*7)+(2*3)+(1*7)=132
132 % 10 = 2
So 1023937-37-2 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.

Visible-Light-Mediated Ring-Opening Strategy for the Regiospecific Allylation/Formylation of Cycloalkanols

Wang, Junlei,Huang, Binbin,Shi, Chengcheng,Yang, Chao,Xia, Wujiong

, p. 9696 - 9706 (2018/09/06)

Here we describe a straightforward and efficient approach for regiospecific introduction of an allyl group into cycloalkanol molecules employing a visible-light-mediated ring-opening strategy. A wide range of distally allylated or formylated ketones is fu
