Check Digit Verification of cas no

The CAS Registry Mumber 74997-32-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,9 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74997-32:
(7*7)+(6*4)+(5*9)+(4*9)+(3*7)+(2*3)+(1*2)=183
183 % 10 = 3
So 74997-32-3 is a valid CAS Registry Number.

INFLUENCE OF THE ANGULAR LINKAGE ON THE MESOMORPHIC PROPERTIES OF CHOLESTERYL ARYLBENZOATES.

Koden,Takenaka,Kusabayashi

, p. 137 - 150 (2007/10/02)

Some cholesteryl esters of arylbenzoic acids incorporating angular linkage such as -Co-, -O-, -S-, and -CH//2-, were prepared, and the transition temperatures and heats determined. The cholesteric-isotropic transition temperatures are likely to correlate with the angular correlation parameters of these carboxylic acid moieties. The mesomorphic phenomena are discussed in terms of the molecular structure and electronic effect of these linkages.
