Check Digit Verification of cas no

The CAS Registry Mumber 62452-73-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,4,5 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 62452-73:
(7*6)+(6*2)+(5*4)+(4*5)+(3*2)+(2*7)+(1*3)=117
117 % 10 = 7
So 62452-73-7 is a valid CAS Registry Number.

Optically active compound and photosensitive resin composition

-

, (2008/06/13)

A photoactive compound is used in combination with a photosensitizer, represented by the following formula (1): A?[(J)m?(X-Pro)]n ??(1) wherein A represents a hydrophobic unit comprising at least one kind of hydrophobic groups selected from a hydrocarbon group and a heterocyclic group, J represents a connecting group, X-Pro represents a hydrophilic group protected by a protective group Pro which is removable by light exposure, m represents 0 or 1, and n represents an integer of not less than 1. The protective group Pro may be removable by light exposure in association with the photosensitizer (especially, a photo acid generator), or may be a hydrophobic protective group. The hydrophilic group may be a hydroxyl group or a carboxyl group. The photoactive compound has high sensitivity to a light source of short wavelength beams, for resist application, therefore, the photoactive compound is advantageously used for forming a pattern with high resolution.

Tolan derivative, liquid crystal composition containing the derivative, and liquid crystal display device having the composition

-

, (2008/06/13)

A tolan derivative of a formula: STR1 where R represents a linear alkyl group having from 1 to 10 carbon atoms; X1, X2 and X3 independently represent a fluorine atom or a hydrogen atom, provided that one of them is necessarily a fluorine atom and the others are hydrogen atoms; and Y represents a nitrile group or a linear alkyl group having from 1 to 10 carbon atoms; and a liquid crystal composition containing the derivatives; and a liquid crystal display device having the composition are produced. The compound is compatible with other liquid crystal compounds, and by blending the compound with ordinary liquid crystal compounds, a liquid crystal composition having a broadened practical temperature range and an enlarged double refraction anisotropy is obtained.

Synthesis and Physical Properties of Asymmetric Diphenyldiacetylenic Liquid Crystals

Meng, H.-H. B.,Dalton, L. R.,Wu, S.-T.

, p. 303 - 314 (2007/10/02)

Fifty-six asymmetric diphenyl-diacetylene liquid crystal homologs including dialkyl, alkyl-alkoxy, cyano-alkyl, chloro-alkyl, fluoro-alkyl, difluoro-alkyl, lateral chloro-substituted fluoro-alkyl (or alkoxy), lateral fluoro-substituted asymmetric dialkyl, and vinyl-alkyl are synthesized and their physical properties evaluated.Among these asymmetric diphenyl-diacetylene liquid crystals, many dialkyl homologs exhibit low melting point, wide nematic range, and low heat of fusion.They are ideal host candidates for formulating eutectic mixtures.The polar groups make important contributions to the phase transition temperature, dielectric anisotropy, refractive indices and viscosity.Detailed effects depend on the position of the substitution.These new liquid-crystals compounds and mixtures are particularly useful for electro-optic modulation of infrared radiation. - Keywords: Diphenyl-diacetylenes, eutectic mixtures, electro-optic modulation, physical properties
