Check Digit Verification of cas no

The CAS Registry Mumber 144331-19-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,3,3 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144331-19:
(8*1)+(7*4)+(6*4)+(5*3)+(4*3)+(3*1)+(2*1)+(1*9)=101
101 % 10 = 1
So 144331-19-1 is a valid CAS Registry Number.

A stereodivergent chirospecific synthesis of (3R) and (3S) 3-hydroxyaspartates by hydroxylation of aspartate diester enolates

Sardina, F. Javier,Paz, Manuel M.,Fernandez-Megia, Eduardo,De Boer, Richard F.,Alvarez, M. Pilar

, p. 4637 - 4640 (2007/10/02)

A chirospecific and stereodivergent synthesis of N-(9-phenylfluorenyl)-3-hydroxyaspartates by hydroxylation of aspartate enolates is described. The stereochemistry of the newly created chiral center is controlled by the nature of the enolate counterion an
