Check Digit Verification of cas no

The CAS Registry Mumber 99677-97-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,7 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99677-97:
(7*9)+(6*9)+(5*6)+(4*7)+(3*7)+(2*9)+(1*7)=221
221 % 10 = 1
So 99677-97-1 is a valid CAS Registry Number.

Aliphatic Liquid Crystals, 6 - Cholesteric 19-Norcholesteryl Esters

Sucrow, Wolfgang,Howard, Susanne

, p. 4341 - 4346 (2007/10/02)

19-Norcholesterol (6a) was prepared on a known route and esterified with 14 aliphatic and 3 aromatic acids.The aliphatic esters 6c - p and the anisate 6r exhibit cholesteric phases broader than those of the corresponding cholesteryl esters.This effect is caused by a lowering of the melting points which is explained with a less stable packing of the crystal lattices.
