85931-57-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 85931-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,9,3 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 85931-57:
(7*8)+(6*5)+(5*9)+(4*3)+(3*1)+(2*5)+(1*7)=163
163 % 10 = 3
So 85931-57-3 is a valid CAS Registry Number.

Synthesis, structure and electrochemical properties of two new unsymmetrical tetrathiafulvalene derivatives

Xu, Ming,Ji, Yong,Zuo, Jing-Lin,Li, Yi-Zhi,You, Xiao-Zeng

, p. 847 - 850 (2005)

Two new unsymmetrical tetrathiafulvalene (TTF) derivatives, 2,3-bis(cyanoethylthio)-6,7-(methylethylenedithio)tetrathiafulvalene (6a) and 2,3-bis(cyanoethylthio)-6,7-(cyclopentodithio)tetrathiafulvalene (6b), have been prepared and characterized by NMR, MS, IR and Elemental analyses. The molecular structures have been determined by X-ray crystallography. Their redox properties have been investigated by cyclic voltammetry in dichloromethane solution and each compound shows two reversible single-electron redox couples.
