Check Digit Verification of cas no

The CAS Registry Mumber 843607-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,3,6,0 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 843607-43:
(8*8)+(7*4)+(6*3)+(5*6)+(4*0)+(3*7)+(2*4)+(1*3)=172
172 % 10 = 2
So 843607-43-2 is a valid CAS Registry Number.

Synthesis and characterization of perfluorohexylated poly(3,4-ethylenedioxythiophene)

Zuo, Liangbin,Qing, Feng-Ling,Meng, Wei-Dong,Huang, Xiaoyu,Zhang, Sen,Wu, Qiang

, p. 1441 - 1446 (2004)

The perfluorohexylated 3,4-ethylenedioxythiophene 5 was prepared via Mitsunobu reaction of perfluorohexylatyed diol 2 with diethyl 3,4-dihydroxythiophenedicarboxylate followed by decarboxylation. The polymerization of 5 was conducted with both oxidative chemical and electrochemical polymerizations. The polymers were characterized by cyclic voltammogram, UV, IR, TGA and DSC.
