Check Digit Verification of cas no

The CAS Registry Mumber 1433846-18-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,3,8,4 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1433846-18:
(9*1)+(8*4)+(7*3)+(6*3)+(5*8)+(4*4)+(3*6)+(2*1)+(1*8)=164
164 % 10 = 4
So 1433846-18-4 is a valid CAS Registry Number.

Organocatalytic enantioselective decarboxylative Michael addition of β-ketoacids to α,β-unsaturated ketones

Kang, Young Ku,Lee, Hyun Joo,Moon, Hyoung Wook,Kim, Dae Young

, p. 1332 - 1335 (2013)

Enantioselective decarboxylative Michael addition reactions promoted by chiral primary amine organocatalysts have been developed, allowing the facile synthesis of the corresponding chiral 1,5-diketones with excellent enantioselectivity (up to 97% ee). The method reported represents a valuable approach of utilizing β-ketoacids as synthetic equivalents of aryl methyl ketones.
