6406-36-6 Usage
Preparation
2-Aminobenzoic acid diazo, in alkaline conditions and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid coupling, its product to diazo, coupled with 2-Hydroxybenzoic acid.Properties and Applications
Dark purplish red. Soluble in water for red, and adequate soluble in alcohol. In the dark for the strong sulfuric acid, diluted as a pale orange-red to brown. The dye solution to join strong hydrochloric acid have red light brown precipitation; Add sodium hydroxide to red light brown.Check Digit Verification of cas no
The CAS Registry Mumber 6406-36-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 6 respectively; the second part has 2 digits, 3 and 6 respectively.Calculate Digit Verification of CAS Registry Number 6406-36:
(6*6)+(5*4)+(4*0)+(3*6)+(2*3)+(1*6)=86
86 % 10 = 6
So 6406-36-6 is a valid CAS Registry Number.
