Check Digit Verification of cas no
The CAS Registry Mumber 3740-58-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,4 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3740-58:
(6*3)+(5*7)+(4*4)+(3*0)+(2*5)+(1*8)=87
87 % 10 = 7
So 3740-58-7 is a valid CAS Registry Number.

Asymmetric olefin isomerization of butenolides via proton transfer catalysis by an organic molecule
Wu, Yongwei,Singh, Ravi P.,Deng, Li
supporting information; experimental part, p. 12458 - 12461 (2011/10/09)
An unprecedented enantioselective and general olefin isomerization was realized via biomimetic proton transfer catalysis with a new chiral organic catalyst. A broad range of mono- and disubstituted β,γ-unsaturated butenolides were transformed into the corresponding chiral α,β- unsaturated butenolides in high enantioselectivity and yield in the presence of as low as 0.5 mol % catalyst. Mechanistic studies have revealed the protonation as the rate-determining step.
