Check Digit Verification of cas no

The CAS Registry Mumber 1421338-38-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,3,3 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1421338-38:
(9*1)+(8*4)+(7*2)+(6*1)+(5*3)+(4*3)+(3*8)+(2*3)+(1*8)=126
126 % 10 = 6
So 1421338-38-6 is a valid CAS Registry Number.

First one-pot organocatalytic synthesis of α-methylene-γ- lactones

Companyo, Xavier,Mazzanti, Andrea,Moyano, Albert,Janecka, Anna,Rios, Ramon

, p. 1184 - 1186 (2013/03/13)

All in one pot: an organocatalytic highly enantioselective synthesis of α-methylene-γ-lactones has been reported. The reaction between protected 2-hydroxymalonates and MBH carbonates is simply catalysed by chiral Lewis bases affording after acid treatment
