Check Digit Verification of cas no

The CAS Registry Mumber 393588-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,3,5,8 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 393588-08:
(8*3)+(7*9)+(6*3)+(5*5)+(4*8)+(3*8)+(2*0)+(1*8)=194
194 % 10 = 4
So 393588-08-4 is a valid CAS Registry Number.

Asymmetric synthesis of α-amino carbonyls (aldehydes, ketones and acids) using lithium (R)-N-benzyl-N-α-methylbenzylamide

Davies,Epstein,Ichihara,Smith

, p. 1599 - 1601 (2001)

The diastereoselective conjugate addition of lithium (R)-N-benzyl-N-α-methylbenzylamide to α,β-unsaturated esters and subsequent enolate hydroxylation, followed by reduction and oxidative cleavage provides a facile route to N,N-protected α-amino aldehydes and ketones. Further manipulation furnishes α-amino acids in high enantiomeric excess.
