Check Digit Verification of cas no
The CAS Registry Mumber 4702-64-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4702-64:
(6*4)+(5*7)+(4*0)+(3*2)+(2*6)+(1*4)=81
81 % 10 = 1
So 4702-64-1 is a valid CAS Registry Number.

Anthraquinone dyestuffs for liquid crystal dielectrics
-
, (2008/06/13)
New anthraquinone dyestuffs of the general formula I STR1 wherein Hal is a halogen atom and the two radicals R are each H or NH2 and the alkyl group has 1-8 C atoms, exhibit a high order parameter and are suitable for use as components of liquid-crystal dielectrics.
ORDER PARAMETERS FOR ISOMERIC PHENYL SUBSTITUTED ANTHRAQUINONE DYES DISSOLVED IN NEMATIC LIQUID CRYSTALS MIXTURES - INFLUENCE OF THE HOST.
Cognard,Hieu Phan,Basturk
, p. 327 - 340 (2007/10/02)
Substitution of the anthraquinone ring system provided dyes suitable for guest-host applications. In general, one seeks to elongate the anthraquinonic system through a fourth ring. Different molecular structures have been proposed which all have similar ordering in the liquid crystalline host. Surprisingly, the 2-p-alkoxyphenyl substituted 1,5 dihydroxy-4, 8-diaminoanthraquinones have a higher order parameter in liquid crystalline mixtures of positive dielectric anisotropy made from cyano substituted moelcules. They lose this property in a system consisting of molecules without cyano groups at the terminii of the molecular axes. The properties of two isomeric substituted anthraquinone dyes in different hosts are compared in order to illustrate the considerable influence that dye-liquid crystal interactions may have on dye order parameter.
