6426-76-2 Usage
Preparation
4-(4-Aminophenyl)benzenamine double nitriding, in alkaline conditions and has 4-Hydroxy-7-(phenylamino)naphthalene-2-sulfonic acid and 4-Amino-5-hydroxynaphthalene-1,3-disulfonic acid coupling.
Properties and Applications
red light blue. Soluble in water for red light blue, also soluble in soluble fiber element, slightly soluble in alcohol, insoluble in other organic solvents. The strong sulfuric acid in blue, diluted dark purple for blue-ray, precipitation. The dye solution to join 10% sodium hydroxide solution is more blue; Add 10% sulfuric acid remains the same.

Check Digit Verification of cas no
The CAS Registry Mumber 6426-76-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6426-76:
(6*6)+(5*4)+(4*2)+(3*6)+(2*7)+(1*6)=102
102 % 10 = 2
So 6426-76-2 is a valid CAS Registry Number.
