Check Digit Verification of cas no

The CAS Registry Mumber 159726-84-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,7,2 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 159726-84:
(8*1)+(7*5)+(6*9)+(5*7)+(4*2)+(3*6)+(2*8)+(1*4)=178
178 % 10 = 8
So 159726-84-8 is a valid CAS Registry Number.

Bis-porphyrin copolymers covalently linked by pyridinium spacers obtained by electropolymerization from β-octaethylporphyrins and pyridyl-substituted porphyrins

Xia, Yun,Schaming, Delphine,Farha, Rana,Goldmann, Michel,Ruhlmann, Laurent

, p. 588 - 596 (2012)

Five bis-porphyrin copolymers have been obtained by an electropolymerization process using zinc β-octaethylporphyrin (ZnOEP) type macrocycles and porphyrins functionalized by several pyridyl groups. This electropolymerization process is based on a nucleophilic attack of the pyridyl groups onto electrogenerated ZnOEP dications at their meso-positions. It is the first time that bis-porphyrin copolymers have been obtained. In this study, the copolymers have been characterized by electrochemistry, UV-visible absorption spectroscopy and atomic force microscopy. In particular, interactions between pyridinium spacers are thoroughly discussed. The Royal Society of Chemistry and the Centre National de la Recherche Scientifique 2012.
