Check Digit Verification of cas no
The CAS Registry Mumber 6250-23-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,5 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6250-23:
(6*6)+(5*2)+(4*5)+(3*0)+(2*2)+(1*3)=73
73 % 10 = 3
So 6250-23-3 is a valid CAS Registry Number.

Some new substituted cyclotriphosphazenes were prepared by reaction of hexachlorocyclotriphosphazene and phenylazophenylazophenol compounds such as p-[p-phenylazo-phenylazo]phenol, p-[p-(o-chlorophenylazo)phenylazo]phenol, p-[p-(p-chlorophenylazo)-phenylazo]phenol, p-[p-(p-methylphenylazo)phenylazo]phenol, and tetrazobenzene-β-naphtol. They are characterized by UV-Vis, FT IR, elemental analysis, and TG, DTG, and DTA.
SYNTHESIS AND PROPERTIES OF SIDE-CHAIN LIQUID CRYSTALLINE POLYMERS CONTAINING AZOBENZENE MESOGENS
Angeloni, Annino Sante,Campagnari, Ilaria,Caretti, Daniele,Carlini, Carlo,Altomare, Angelina,et al.
, p. 171 - 178 (2007/10/02)
The synthesis and phase behaviour of side-chain liquid crystalline polymers containing the trans-azobenzene mesogenic unit are described.Depending on the structure of the repeating unit, the polymers give rise to nematic mesophases and/or different smectic modifications.The liquid crystalline properties of the polymers are discussed with respect to the influence of the polymer backbone nature, chemical constitution and length of the spacer segment, and type and length of the para substituent on the azobenzene moiety.Indications on the UV absorption and photoisomerization behaviour of trans-azobenzene containing polymers are also provided.
