Check Digit Verification of cas no

The CAS Registry Mumber 217322-54-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,3,2 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 217322-54:
(8*2)+(7*1)+(6*7)+(5*3)+(4*2)+(3*2)+(2*5)+(1*4)=108
108 % 10 = 8
So 217322-54-8 is a valid CAS Registry Number.

Resolution of racemic 3-aryloxy-1-nitrooxypropan-2-ols by lipase-catalyzed enantioselective acetylation

Pchelka, Beata Krystyna,Loupy, Andre,Plenkiewicz, Jan,Petit, Alain,Blanco, Luis

, p. 2109 - 2119 (2007/10/03)

Both (R)- and (S)-enantiomers of 3-aryloxy-1-nitrooxypropan-2-ols (R)-(-)-1, (S)-(+)-2 were prepared in high enantiomeric excess by lipase from Pseudomonas cepacia (Amano PS) or Pseudomonas fluorescens (Amano AK)-catalyzed acetylation of racemic alcohols 1a-g with vinyl acetate in n-hexane at 4 or 22°C. The enantioselectivity of this transformation was dependent on the substitution pattern of the aryl ring with E-values ranging from 31 to 111.
