70904-65-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70904-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,0 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70904-65:
(7*7)+(6*0)+(5*9)+(4*0)+(3*4)+(2*6)+(1*5)=123
123 % 10 = 3
So 70904-65-3 is a valid CAS Registry Number.

Synthesis of crescent aromatic oligoamides

Yuan, Lihua,Sanford, Adam R.,Feng, Wen,Zhang, Aimin,Zhu, Jin,Zeng, Huaqiang,Yamato, Kazuhiro,Li, Minfeng,Ferguson, Joseph S.,Gong, Bing

, p. 10660 - 10669 (2007/10/03)

This article describes the synthetic procedures for the preparation of crescent (and helical) aromatic oligoamides developed in recent years in our laboratory. The large-scale preparation of a variety of monomers derived from various tetrasubstituted benzenes is presented. Three different strategies for constructing various oligomers consisting of meta- and meta/para-linked benzene residues are discussed. Factors affecting coupling efficiency and yields are analyzed. The developed synthetic methods have provided the basis for the preparation of longer oligomers and for the development of solid-phase synthesis.

Hypoxia-selective antitumor agents. 13. Effects of acridine substitution on the hypoxia-selective cytotoxicity and metabolic reduction of the bis- bioreductive agent nitracrine N-oxide

Lee,Wilson,Ferry,Van Zijl,Pullen,Denny

, p. 2508 - 2517 (2007/10/03)

A series of nuclear-substituted derivatives of nitracrine N-oxide (2; a bis-bioreductive hypoxia-selective cytotoxin) were prepared and evaluated, seeking analogues of lower nitroacridine reduction potential. Disubstitution with Me or OMe groups at the 4-
