Check Digit Verification of cas no

The CAS Registry Mumber 120926-88-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,2 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 120926-88:
(8*1)+(7*2)+(6*0)+(5*9)+(4*2)+(3*6)+(2*8)+(1*8)=117
117 % 10 = 7
So 120926-88-7 is a valid CAS Registry Number.

The Charge Storage Mechanism of Conducting Polymers: A Voltammetric Study on Defined Soluble Oligomers of the Phenylene-Vinylene Type

Heinze, Juergen,Mortensen, John,Muellen, Klaus,Schenk, Rainer

, p. 701 - 703 (1987)

The reductive charging-discharging behaviour of several newly synthesized soluble oligo-p-phenylene-vinylenes was studied by cyclic voltammetry; the results show that both the number of redox states and the magnitude of their energetic interaction depend

Singlet-State Diabatic and Adiabatic Cis-Trans Photoisomerizations of 4,4'-Bis(3,5-di-tert-butylstyryl)stilbenes

Sandros, Kjell,Sundahl, Mikael,Wennerstroem, Olof

, p. 5291 - 5294 (1993)

The mechanism for photoisomerization of the six isomers, 1-6, of 4,4'-bis(3,5-di-tert-butylstyryl)stilbene has been investigated.The isomerizations always proceed from cis to trans configurations, and single isomerizations are dominating.By increasing the solvent polarity from methylcyclohexane to toluene and to methylene chloride, an increase of the quantum yields, particularly for isomerization of the central double bond, was observed.Thus, there is a selectivity effect; in methylcyclohexane isomerization of an edge double bond is favored, while in methylene chloride isomerization of a middle double bond is favored.There is also clear evidence of an adiabatic contribution to the isomerization of the double bond.The diabatic part of the isomerization quantum yield is most strongly affected by the solvent.A solvent with higher polarity lowers the energy of an excited state with 90 deg twist to the double bond; that is, a polar solvent will stabilize a zwitterionic excited singlet state.

Models for the charging of extended π chains

Schenk, Rainer,Gregorius, Heike,Meerholz, Klaus,Heinze, Jürgen,Mülen, Klaus

, p. 2634 - 2647 (2007/10/02)

The syntheses as well as the chemical and electrochemical reduction of a series of novel oligo(phenylenevinylenes) are described. The extended π chains are built up by sequences of Wittig reactions, and the corresponding polyanions are generated by electr
