Check Digit Verification of cas no

The CAS Registry Mumber 66841-45-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,8,4 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 66841-45:
(7*6)+(6*6)+(5*8)+(4*4)+(3*1)+(2*4)+(1*5)=150
150 % 10 = 0
So 66841-45-0 is a valid CAS Registry Number.

PREPARATION OF BOTH ENANTIOMERS OF (1R*, 2S*)-1-CYCLOHEXYL-1,2-PROPANEDIOL FROM THE COMMERCIAL NEUBERG'S KETOL

Cervinka, Otakar,Struzka, Vladimir

, p. 2685 - 2691 (2007/10/02)

Both the optically pure enantiomers of (1R*,2S*)-1-cyclohexyl-1,2-propanediol (II) were prepared from commercial (R)-(-)-1-phenyl-1-hydroxy-2-propanone (I; Neuberg's ketol). (1R,2S)-(+)-1-Cyclohexyl-1,2-propanediol(+)-II) was obtained in 19percent total yield, its (1S,2R)-enantiomer ((-)II) in 8percent yield.Both diols, as well as their precursors, enantiomeric (1R*,2S*)-1-phenyl-1,2-propanediols (IIIa), are suitable chiral synthons.
