Check Digit Verification of cas no

The CAS Registry Mumber 1428485-88-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,4,8 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1428485-88:
(9*1)+(8*4)+(7*2)+(6*8)+(5*4)+(4*8)+(3*5)+(2*8)+(1*8)=194
194 % 10 = 4
So 1428485-88-4 is a valid CAS Registry Number.

Asymmetric michael addition of N-tert-butanesulfinyl imidate with α,β-unsaturated diesters: Scope and application to the synthesis of indanone derivatives

Wang, Jinfang,Zhou, Yu,Zhang, Lei,Li, Zeng,Chen, Xianjie,Liu, Hong

, p. 1508 - 1511 (2013/06/27)

An additive-free and highly diastereoselective Michael addition reaction of an N-tert-butanesulfinyl imidate to α,β-unsaturated diesters has been developed using LDA as a base with good to excellent yields. The utility of this chemistry is further demonstrated by the asymmetric synthesis of 3-substituted indanone derivatives 8a, 8d, 8e, and 8i with high enantiomeric excess, which are potential building blocks for preparing biologically active lead compounds.
