77477-90-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77477-90-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,7 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77477-90:
(7*7)+(6*7)+(5*4)+(4*7)+(3*7)+(2*9)+(1*0)=178
178 % 10 = 8
So 77477-90-8 is a valid CAS Registry Number.

Controllable Fabrication of Various Supramolecular Nanostructures Based on Nonamphiphilic Azobenzene Derivatives and Pillar[6]arene

Qin, Shan,Xiong, Shuhan,Han, Yang,Hu, Xiao-Yu,Wang, Leyong

, p. 107 - 111 (2015)

Various novel types of supramolecular nanostructures formed by nonamphiphilic azobenzene derivatives, G1 or G2 have been successfully fabricated, where G2 is structurally similar with G1 but an extra phenoxy group is connected with the azobenzene motif. M

Phthalonitriles containing ester groups and copper phthalocyanines based on them

Tikhomirova,Maizlish,Shaposhnikov

scheme or table, p. 768 - 772 (2011/08/09)

Phthalonitriles containing ester groups were obtained by acylation of 4-hydroxyphthalonitrile and esterification of 4-(p-carboxyphenyloxy) phthalonitriles. On the basis of these phthalonitriles the respective copper phthalocyanines were synthesized. Spectral and some other physical and chemical properties of the synthesized compounds were investigated.

4-acyloxy- and 4-acylaminophthalonitriles and phthalocyanines based thereon

Tararykina,Maizlish,Galanin,Shaposhnikov,Bykova,Usol'tseva

, p. 1719 - 1725 (2008/09/18)

Reactions of 4-hydroxy- and 4-aminophthalonitriles with substituted benzoyl chlorides gave the corresponding N- and O-benzoyl derivatives, and the latter were used to obtain copper and nickel phthalocyanine complexes. Effect of the substituents in the latter on their electronic absorption spectra was studied. The obtained complexes were found to undergo association in organic solvents.
