Check Digit Verification of cas no
The CAS Registry Mumber 1533-65-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,3 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1533-65:
(6*1)+(5*5)+(4*3)+(3*3)+(2*6)+(1*5)=69
69 % 10 = 9
So 1533-65-9 is a valid CAS Registry Number.

Polarographic Behaviour of Some 3-Pyridylazo Dyes
Issa, Y. M.,El-anadouli, B. E.,El-shetary, B. A.

The polarographic behaviour of some azo dyes containing 3-pyridyl moiety has been investigated in 40percent ethanolic buffers covering the pH range 3-12.The number of waves depends on the part of the dye attached to the 3-pyridylazo moiety.If this part is 8-quinolinol, two waves are observed, while one wave is obtained if it is a phenol or naphthol derivative.However, this one wave splits into daughters in compounds containing sulphonic acid group due to adsorption of the dye molecules and reduction of the adsorbed molecules at lower potentials.The reduction corresponds to the consumption of four electrons leading to the amine stage.The second wave in the quinoline compound is due to two-electron reduction of the quinoline moiety.A general mechanism for the reduction process is given.
