Check Digit Verification of cas no
The CAS Registry Mumber 41122-71-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,1,2 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 41122-71:
(7*4)+(6*1)+(5*1)+(4*2)+(3*2)+(2*7)+(1*1)=68
68 % 10 = 8
So 41122-71-8 is a valid CAS Registry Number.

Liquid crystals of the 4-alkyl-4'-cyanobiphenyl group were synthesized without the use of copper cyanide. 4-Alkyl-4'-formylbiphenyls and the 4-formyloximes of 4'-alkylbiphenyl, which possess a liquid-crystalline state, were isolated.Beginning with the pentyl homolog, they form an enantiotropic nematic phase, and beginning with octyl homolog they also form a smectic meso phase.
