Check Digit Verification of cas no
The CAS Registry Mumber 125677-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,6,7 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 125677-99:
(8*1)+(7*2)+(6*5)+(5*6)+(4*7)+(3*7)+(2*9)+(1*9)=158
158 % 10 = 8
So 125677-99-8 is a valid CAS Registry Number.

Nonmetal-catalyzed iodination of arenes with iodide and hydrogen peroxide
Iskra, Jernej,Stavber, Stojan,Zupan, Marko
, p. 1869 - 1873 (2004)
Oxidative iodination of arenes was carried out with one equivalent of KI and two equivalents of 30% hydrogen peroxide in MeOH in the presence of strong acid. Reactions of various substituted anisoles, phenols and anilines, as well as mesitylene and uracil, were selective and effective with very good yields of isolated halogenated aromatic molecules.
Synthesis and characterization of a main-chain donor-acceptor type low-bandgap polymer by post-functionalization of a poly(arylene ethynylene)
Huang, Wenyi
, p. 42 - 48 (2014/08/18)
I report a facile synthetic route for synthesizing a main-chain donor-acceptor type polymer containing strong electron donating dialkylamino groups and strong electron accepting 1,1,4,4-tetracyanobuta-1,3-diene (TCBD) units. To accomplish this, an electron donating monomer 4,6-diethynyl-N,N,N,N- tetrahexylbenzene-1,3-diamine was successfully synthesized by converting two carbaldehyde groups in the corresponding monomer into acetylene groups using lithium trimethylsilyldiazomethane via Colvin rearrangement. This electron donating monomer was then polymerized with a carbonyl-activated diiodide monomer to afford an electron-donating π-conjugated precursor polymer with a reasonably high molecular weight, which was further reacted with TCNE via cycloaddition/retroelectrocyclization reaction under mild conditions to afford the target polymer with a low bandgap energy (Egopt=1.40eV and EgCV=1.10eV) arising from strong intramolecular charge-transfer interactions between electron donors and acceptors in the polymer.
