Check Digit Verification of cas no

The CAS Registry Mumber 174591-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,5,9 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 174591-33:
(8*1)+(7*7)+(6*4)+(5*5)+(4*9)+(3*1)+(2*3)+(1*3)=154
154 % 10 = 4
So 174591-33-4 is a valid CAS Registry Number.

High-pressure and thermally induced asymmetric Diels-Alder cycloadditions of heterosubstituted dienes to homochiral α,β-didehydro amino acid derivatives

Ortuno, Rosa M.,Ibarzo, Javier,D'Angelo, Jean,Dumas, Francoise,Alvarez-Larena, Angel,Piniella, Joan F.

, p. 127 - 138 (1996)

An amino pentenoate and an unsaturated oxazolone have shown to be suitable homochiral dienophiles to be reacted with electron-rich heterosubstituted dienes. High-pressure and thermal activation have been studied for these cycloadditions. The adducts obtained are polyfunctional building blocks useful for the synthesis of enantiopure cyclohexane amino acids and related products.
