675832-95-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 675832-95-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,5,8,3 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 675832-95:
(8*6)+(7*7)+(6*5)+(5*8)+(4*3)+(3*2)+(2*9)+(1*5)=208
208 % 10 = 8
So 675832-95-8 is a valid CAS Registry Number.

Synthesis and Characterisation of Unsymmetrical Porphyrazines Containing Bis(hydroxyethylthio) Substituents

Kalkan, Ayfer,Bayir, Zehra A.

, p. 1555 - 1560 (2003)

Unsymmetrical porphyrazines bearing a single peripheral bis(hydroxyethylthio) moiety were synthesised by mixed condensation of bis(2-hydroxyethylthio)maleonitrile and phthalonitrile. Complexation of the thioether groups of metal-free porphyrazine with PdCl2 further lowered the intensity of the Q-band absorption of the porphyrazine core. The new compounds were characterised by elemental analyses, IR, 1H NMR, UV-Vis, and mass spectra.
