97206-27-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 97206-27-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,0 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 97206-27:
(7*9)+(6*7)+(5*2)+(4*0)+(3*6)+(2*2)+(1*7)=144
144 % 10 = 4
So 97206-27-4 is a valid CAS Registry Number.

Aromatic fluorination effect on the mesomorphic properties of discotic liquid crystal of alkoxybenzoyloxytriphenylene

Sasada, Yasuyuki,Monobe, Hirosato,Ueda, Yasukiyo,Shimizu, Yo

, p. 584 - 585 (2007)

Two homologues, C6F4 and C10F4 having 2,3,5,6-tetrafluorophenylene moieties were synthesized and investigated on the mesomorphic behavior. It was revealed that these exhibit a hexagonal columnar (Colh) phase, and this mesomorphism is quite diff

Mesomorphic Properties of Some New Fluorinated Liquid Crystals: the 4-n-Alkoxyperfluorobenzoate Series and Trifluoromethylbiphenyl Derivatives

Barny, P. le,Ravaux, G.,Dubois, J. C.,Parneix, J. P.

, p. 413 - 430 (2007/10/02)

We describe here the synthesis, the mesomorphic and the dielectric properties of two families of fluorinated compounds: the 4-alkoxyperfluorobenzoic acid 4'-hydroxy-4-cyanobiphenyl esters and the 4-trifluoromethyl-4'-substituted biphenyl derivatives.Some compounds exhibit only a wide temperature nematic range, while others have a wide temperature smectic A range with or without a nematic mesophase.These compounds are possible additives to mixtures of interest for displays.
