Check Digit Verification of cas no

The CAS Registry Mumber 1184944-96-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,4,9,4 and 4 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1184944-96:
(9*1)+(8*1)+(7*8)+(6*4)+(5*9)+(4*4)+(3*4)+(2*9)+(1*6)=194
194 % 10 = 4
So 1184944-96-4 is a valid CAS Registry Number.

Resolution and absolute configuration of some a-aminoacetals: En route to enantiopure N-protected a-aminoaldehydes

Albalat-Serradeil, Muriel,Primazot, Geraldine,Wilhelm, Didier,Vallejos, Jean-Claude,Vanthuyne, Nicolas,Roussel, Christian

, p. 687 - 696 (2012/09/22)

The first successful resolution of rac-a-aminoacetals via diastereoisomeric salt formation with optically pure N-protected aminoacids is reported. The absolute configuration assignment of a-aminoacetal enantiomers is performed by an entirely non-racemizing chemical correlation method involving N-protection and a new efficient hydrolysis step followed by a reduction of the resulting N-protected a-aminoaldehyde intermediates. A racemization method of optically enriched a-aminoacetals is exemplified to allow valorisation of both enantiomers. Springer-Verlag 2011.
