139058-83-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139058-83-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,5 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139058-83:
(8*1)+(7*3)+(6*9)+(5*0)+(4*5)+(3*8)+(2*8)+(1*3)=146
146 % 10 = 6
So 139058-83-6 is a valid CAS Registry Number.

2,2'-Disubstituted biphenyls: Synthesis and suppressive effect against carbon tetrachloride-induced liver injury

Kondo,Takahashi,Ohmizu,Matsumoto,Taguchi,Iwasaki

, p. 62 - 66 (1994)

2,2'-Disubstituted biphenyl compounds (1-15) were synthesized by using the Ullmann coupling reaction as a key step. The suppressive effect of these compounds against CCl4-induced liver injuries in mice was evaluated. An unsymmetrical biphenyl (

A new synthesis of unsymmetrical diphenic acid derivatives: Template-directed intramolecular Ullmann coupling reaction

Takahashi, Masami,Kuroda, Tooru,Ogiku, Tsuyosi,Ohmizu, Hiroshi,Kondo, Kazuhiko,Iwasaki, Tameo

, p. 6919 - 6922 (2007/10/02)

Intramolecular Ullmann coupling reaction of the diesters (6, 9), which were prepared by regioselective acylation of salicyl alcohol by using the two different substituted 2-iodobenzoyl chlorides, afforded the unsymmetrical diphenic acid derivatives (7, 10
