Check Digit Verification of cas no

The CAS Registry Mumber 900493-82-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,0,4,9 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 900493-82:
(8*9)+(7*0)+(6*0)+(5*4)+(4*9)+(3*3)+(2*8)+(1*2)=155
155 % 10 = 5
So 900493-82-5 is a valid CAS Registry Number.

Asymmetric allylic alkylation of cyclic vinylogous esters and thioesters by Pd-catalyzed decarboxylation of enol carbonate and β-ketoester substrates

Trost, Barry M.,Bream, Robert N.,Xu, Jiayi

, p. 3109 - 3112 (2007/10/03)

(Chemical Equation Presented) Excellent yields and enantioselectivities were achieved for the palladium-catalyzed asymmetric allylic alkylation of vinylogous thioesters. The close-to-neutral reaction conditions ensure that this reaction can tolerate a wide range of functionalities. Furthermore, this approach provides a convenient protocol for the synthesis of synthetically important α,α- and γ,γ-di-substituted cycloalkenones.
