Check Digit Verification of cas no

The CAS Registry Mumber 1345824-05-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,5,8,2 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1345824-05:
(9*1)+(8*3)+(7*4)+(6*5)+(5*8)+(4*2)+(3*4)+(2*0)+(1*5)=156
156 % 10 = 6
So 1345824-05-6 is a valid CAS Registry Number.

A Chiral Pentafluorinated Isopropyl Group via Iodine(I)/(III) Catalysis

Meyer, Stephanie,H?fliger, Joel,Sch?fer, Michael,Molloy, John J.,Daniliuc, Constantin G.,Gilmour, Ryan

, p. 6430 - 6434 (2021/02/26)

An I(I)/(III) catalysis strategy to construct an enantioenriched fluorinated isostere of the iPr group is reported. The difluorination of readily accessible α-CF3-styrenes is enabled by the in situ generation of a chiral ArIF2 species to forge a stereocentre with the substituents F, CH2F and CF3 (up to 95 %, >20:1 vicinal:geminal difluorination). The replacement of the metabolically labile benzylic proton results in a highly preorganised scaffold as was determined by X-ray crystallography (π→σ* and stereoelectronic gauche σ→σ* interactions). A process of catalyst editing is disclosed in which preliminary validation of enantioselectivity is placed on a structural foundation.
