142781-56-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 142781-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,8 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142781-56:
(8*1)+(7*4)+(6*2)+(5*7)+(4*8)+(3*1)+(2*5)+(1*6)=134
134 % 10 = 4
So 142781-56-4 is a valid CAS Registry Number.

Synthesis and Characterization of Push-Pull Porphyrins

Chen, Chin-Ti,Hsieh, Shin Jung

, p. 23 - 31 (2007/10/03)

A series of "push-pull" porphyrins with 4-nitrophenyl and 4-aminophenyl substituents were synthesized and separated by flash column chromatographic techniques. They were fully characterized by elemental analysis, FAB-MS, FTIR, UV-visible, and 1H NMR spectroscopies. The unsymmetrical π-electron distribution of the porphyrins caused by the donor (amino) and acceptor (nitro) substituents were investigated by 1H NMR technique. The pyrrole-H resonance positions can be correlated to the Hammett oσ constants of the substituents. Although with strong donor and acceptor substituents, UV-visible spectra show the push-pull porphyrins have rather weak solvatochromism and hence limited intramolecular charge-transfer character.
