Calculate Digit Verification of CAS Registry Number 74256-64:
(7*7)+(6*4)+(5*2)+(4*5)+(3*6)+(2*6)+(1*4)=137
137 % 10 = 7
So 74256-64-7 is a valid CAS Registry Number.

APPLICATION OF LIQUID CRYSTALS FOR GAS-LIQUID CHROMATOGRAPHY.

Sakagami,Nakamizo

, p. 1157 - 1158 (1984)

A liquid crystalline homologous series of N- left bracket 4-(4-alkoxybenzoyloxy)benzylidene right bracket -4-cyanoanilines was applied as a stationary liquid phase for the gas-liquid chromatographic separation of various positional isomers. It is shown that the nematic phase has higher selectivity for several positional isomers compared with the other mesomorphic phases.
