Check Digit Verification of cas no

The CAS Registry Mumber 1217341-14-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,3,4 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1217341-14:
(9*1)+(8*2)+(7*1)+(6*7)+(5*3)+(4*4)+(3*1)+(2*1)+(1*4)=114
114 % 10 = 4
So 1217341-14-4 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

scheme or table, 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.
