19728-45-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19728-45-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,2 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19728-45:
(7*1)+(6*9)+(5*7)+(4*2)+(3*8)+(2*4)+(1*5)=141
141 % 10 = 1
So 19728-45-1 is a valid CAS Registry Number.

Electrochemical oxidation of probucol in anhydrous acetonitrile

Nesmerak, Karel,Nemec, Ivan,Sticha, Martin,Gabriel, Jiri,Mirceski, Valentin

, p. 1100 - 1110 (2007/10/03)

Electrochemical oxidation of probucol in anhydrous acetonitrile was studied as a model of the metabolic oxidation of the substance. The study was performed by DC voltammetry, potentiostatic coulometry, cyclic voltammetry and preparative electrolysis. Probucol gives a single anodic wave E1/2 = 0.92 V. Cyclic voltammetry showes that its electrooxidation proceeds by formation of probucol radical. 2,6-Di-tert-butyl-4-(isopropylsulfanyl)phenol, 2,6-di-tert-butyl-4-sulfanylphenol, 2,6-di-tert-butyl-4-methylphenol and 2,6-di-tert-butylphenol were isolated as products of electrochemical oxidation.
