20608-85-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20608-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,0 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20608-85:
(7*2)+(6*0)+(5*6)+(4*0)+(3*8)+(2*8)+(1*5)=89
89 % 10 = 9
So 20608-85-9 is a valid CAS Registry Number.

In situ synthesis of electroactive conjugated microporous fullerene films capable of supercapacitive energy storage

Sun, Mingxiao,Kuang, Puxing,Qin, Leiqiang,Gu, Cheng,Xie, Zengqi,Ma, Yuguang

, p. 9602 - 9605 (2017)

We describe a general strategy for synthesizing conjugated microporous fullerene thin films via a high-throughput, efficient and controllable thiophene-based electropolymerization. By virtue of the ambipolar redox charge/discharge of the films, we showed the microporous fullerene films as outstanding pseudocapacitor materials with high capacity and wide potential windows.

Iron-catalyzed oxidative coupling of arylboronic acids with benzene derivatives through homolytic aromatic substitution

Uchiyama, Nanase,Shirakawa, Eiji,Nishikawa, Ryo,Hayashi, Tamio

supporting information; experimental part, p. 11671 - 11673 (2011/12/05)

Fe(OTf)3-1,10-phenanthroline catalyzes oxidative coupling of arylboronic acids with benzene derivatives using t-BuOOt-Bu as an oxidant. The reaction proceeds through homolytic aromatic substitution with aryl radicals generated from arylboronic acids and t-BuO.

Preparation of unsymmetrical 1,4-bis[2-ethynyl-3-thienyl]benzene derivative

Toyota, Kozo,Tsuji, Yasutomo,Okada, Kazuyuki,Morita, Noboru

experimental part, p. 127 - 138 (2009/05/07)

Unsymmetrically substituted 1,4-bis(2-ethynyl-3-thienyl)benzene derivative was prepared, utilizing 1-bromo-4-(2-iodo-3-thienyl)benzene and 5-alkyl-3-bromo-2-ethynylthiophene derivatives as key intermediates.
