108761-80-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 108761-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,7,6 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 108761-80:
(8*1)+(7*0)+(6*8)+(5*7)+(4*6)+(3*1)+(2*8)+(1*0)=134
134 % 10 = 4
So 108761-80-4 is a valid CAS Registry Number.

Synthesis and photophysical properties of 2,6-dicyano-p-phenylenediamine

Zahid, Muhammad,Rosspeintner, Arnulf,Angulo, Gonzalo,Grampp, Günter,Jacques, Patrice,Mansha, Asim

, p. 54 - 63 (2011)

The photophysical and electrochemical properties of p-phenylenediamine (PPD) are strongly affected by the addition of cyano groups to the aromatic ring. In 2,3,5,6-tetracyano-p-phenylenediamine (TCPPD) the photophysics is governed mostly by the solvent basicity (β) whereas in 2,6-dicyano-N,N, N′,N′-tetramethyl-p-phenylenediamine (DCTMPPD) by the solvent polarity/polarizability (π*). In order to study the interactions of cyano-substituted PPDs with the solvent molecules in more detail as well as to clarify the role and origin of hydrogen bonding differences for TCPPD and DCTMPPD, another cyano substituted PPD, 2,6-dicyano-p-phenylenediamine (DCPPD) has been synthesized. The photophysical properties have been measured in a wide range of solvents. The fluorescence lifetimes (from 14 ns to 20 ns) and quantum yields (from 0.7 to 0.85) are not very sensitive to the environment. The solvatochromism is analyzed by a linear solvation energy relationship (LSER) using parameters developed by Kamlet, Taft and co-workers. It has been found that both absorption and emission of DCPPD depend on specific as well as non-specific interactions of the solute with the solvent molecules. The ground and excited state pKa values for DCPPD have also been determined.
