Check Digit Verification of cas no
The CAS Registry Mumber 19937-49-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,3 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19937-49:
(7*1)+(6*9)+(5*9)+(4*3)+(3*7)+(2*4)+(1*9)=156
156 % 10 = 6
So 19937-49-6 is a valid CAS Registry Number.

Structural aspects of nucleation inhibitors for diastereomeric resolutions and the relationship to Dutch resolution
Leeman, Michel,Brasile, Giuseppina,Gelens, Edith,Vries, Ton,Kaptein, Bernard,Kellogg, Richard
, p. 1287 - 1290 (2008/12/22)
You say you want a resolution: Nucleation inhibitors for the resolution of diastereomers by selective crystallization have been designed and tested. The resolution of racemic 3-methoxyphenylethylamine was optimized with (S)-mandelic acid as the resolving agent (see scheme). Multifunctional inhibitors are particularly effective. (Chemical Equation Presented).
