Check Digit Verification of cas no

The CAS Registry Mumber 503273-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,2,7 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 503273-40:
(8*5)+(7*0)+(6*3)+(5*2)+(4*7)+(3*3)+(2*4)+(1*0)=113
113 % 10 = 3
So 503273-40-3 is a valid CAS Registry Number.

Stereocontrolled synthesis of bicyclic lactone derivatives via tungsten-mediated [3 + 2] cycloaddition of epoxides with a tethered alkynyl group

Madhushaw, Reniguntala J.,Li, Chien-Le,Su, Haw-Lih,Hu, Chu-Chen,Lush, Shie-Fu,Liu, Rai-Shung

, p. 1872 - 1877 (2003)

In the presence of BF3·Et2O, alkynyltungsten complexes underwent [3 + 2] cycloaddition with tethered epoxides to give bicyclic γ-lactones efficiently. Only one diastereomeric product was formed despite the presence of three stereogen
