Check Digit Verification of cas no
The CAS Registry Mumber 60904-32-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,9,0 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 60904-32:
(7*6)+(6*0)+(5*9)+(4*0)+(3*4)+(2*3)+(1*2)=107
107 % 10 = 7
So 60904-32-7 is a valid CAS Registry Number.

Spectrophotometric Determination of Aromatic Amines by the Diazotization-Coupling Technique with 8-Amino-1-hydroxynaphthalene-3,6-disulfonic Acid and N-(1-Naphthyl)ethylenediamine as the Coupling Agents
Norwitz, George,Keliher, Peter N.
, p. 807 - 809 (2007/10/02)
A comprehensive study is made of the application of the diazotization-coupling spectrophotometric technique to the determination of diverse aromatic amines, using H-acid (8-amino-1-hydroxynaphthalene-3,6-disulfonic acid) and N-(1-naphthyl)ethylenediamine (also called N-(1-naphthalenyl)-1,2-ethanediamine or N-na) as the coupling agents.The methods were tested successfully on halogenate anilines, 2,4-dichloroaniline, nitroanilines, methylanilines, aminobenzoic acids, aminobenzenesulfonic acids, sulfanilamide, and certain other substituted anilines.The methods are not rec ommended for phenylenediamines and aminophenols, which produce little or no color.The aromatic amines containing negative groups tend to couple and produce colors more readily than aromatic amines not containing such groups.The amount of reagent and time required for full color development is less for aromatic amines containing negative groups, specially for the N-na method.Both methods are about equal in accuracy but the N-na mathod is on the average about 1.6 times more sensitive than the H-acid method.
