Check Digit Verification of cas no

The CAS Registry Mumber 1340343-75-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,0,3,4 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1340343-75:
(9*1)+(8*3)+(7*4)+(6*0)+(5*3)+(4*4)+(3*3)+(2*7)+(1*5)=120
120 % 10 = 0
So 1340343-75-0 is a valid CAS Registry Number.

, (2021/12/13)

An efficient oxytrifluoromethylation of 1-aryl-substituted allyl alcohols has been developed using Togni's reagent II as a trifluoromethylation reagent and copper(I) chloride as a catalyst. This reaction proceeded through a one-pot process of trifluoromet

Copper-catalysed ring-opening trifluoromethylation of cyclopropanols

, p. 7159 - 7163 (2015/07/01)

A copper-catalysed ring-opening trifluoromethylation reaction of cyclopropanols has been developed. Various β-trifluoromethyl ketones are obtained in good to excellent yields under mild reaction conditions. The present method also exhibits good functional-group compatibility. The mechanism of this new ring-opening trifluoromethylation reaction was investigated by radical trapping reactions.
