Check Digit Verification of cas no

The CAS Registry Mumber 70279-22-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,7 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 70279-22:
(7*7)+(6*0)+(5*2)+(4*7)+(3*9)+(2*2)+(1*2)=120
120 % 10 = 0
So 70279-22-0 is a valid CAS Registry Number.

Metal Exchange Reaction of Cd(II) 5,10,15,20-Tetra(4-chlorophenyl)porphyrinate with Copper and Zinc Chlorides in DMSO

Zvezdina,Chizhova,Mamardashvili, N. Zh.

, p. 2105 - 2110 (2020)

Abstract: The metal exchange reactions of Cd(II)5,10,15,20-tetra(4-chlorophenyl)porphyrinate with CuCl2and ZnCl2 in DMSO were studied by the spectrophotometricmethod. The kinetic parameters of the metal exchange reactions were determined.A possible reaction mechanism was proposed. Zinc(II) and copper(II)5,10,15,20-tetra(4-chlorophenyl)porphyrinates were synthesized by the complexformation reactions of zinc(II) and copper(II) acetates with5,10,15,20-tetra(4-chlorophenyl)porphyrin and by metal exchange of its cadmiumcomplex with ZnCl2 and CuCl2 indimethylformamide. The resulting compounds were identified by electronicabsorption and 1H NMR spectroscopy and massspectrometry methods.
