Check Digit Verification of cas no
The CAS Registry Mumber 3543-02-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,4 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3543-02:
(6*3)+(5*5)+(4*4)+(3*3)+(2*0)+(1*2)=70
70 % 10 = 0
So 3543-02-0 is a valid CAS Registry Number.

ETUDE PHYSICOCHIMIQUE DE LA DIHYDROXY-3,5 PYRIDINE ET DES ACIDES HYDROXYPYRIDINESULFONIQUES OBTENUS PAR FUSION ALCALINE DU PYRIDINEDISULFONATE-3,5 DE POTASSIUM

The 3,5-dihydroxypyridine may be obtained with an excellent yield by an two-stepped alkaline fusion of potassium pyridine-3,5 disulphonate.Several hydroxypyridinesulphonics acids may be obtained also following others experimentals conditions.UV spectra off all the ionisation states of those molecules were determined and all the acidity constants, in aqueous solutions, were measured.In a general way, Sulphonates (or sulphonics) substituents strenghten the acidity of both hydroxypyridines and pyridinium cations, and cause hyper- and bathochrome shift of the UV spectra.Contrary to the previous conclusion reported in the litterature, and mainly based on wrong spectrophotometrics data, the 3,5-dihydroxypyridine behave in some cases as zwitterionic form (ca. 100 percent for the monoanion and ca. 50 percent for the neutral molecule in aqueous solution).
