Check Digit Verification of cas no

The CAS Registry Mumber 70565-67-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,6 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 70565-67:
(7*7)+(6*0)+(5*5)+(4*6)+(3*5)+(2*6)+(1*7)=132
132 % 10 = 2
So 70565-67-2 is a valid CAS Registry Number.

Mesyloxy-group migration as the stereoselective preparation method of various functionalized olefins and its reaction mechanism

Yamazaki, Takashi,Hiraoka, Shuichi,Sakamoto, Johei,Kitazume, Tomoya

, p. 743 - 746 (2007/10/03)

It was demonstrated that mesylation of appropriate γ,γ-difluorinated allylic alcohols under usual conditions furnished the corresponding α,γ-difluorinated allylic mesylates, possibly by way of 1,3-mesyloxy-group migration after formation of the expected "normal" intermediates, γ,γ-difluorinated allylic mesylates. This rearrangement was conveniently applied to the construction of trisubstituted allylic alcohols, α,β-unsaturated esters, amides, or ketones in good to excellent chemical yields with exclusive E selectivities.

Synthesis of Carbon and Phosphorus Esters of α-Fluoro Alcohols
