5610-64-0 Usage
Chemical Properties
black powder
Preparation
4-Amino-3-hydroxy-7-nitronaphthalene-1-sulfonic acid diazo, and Naphthalen-2-ol matches, will result in aqueous solution with formic acid chromium common heating, in 115 ℃ keep 2 hours, and then into the same batch of have no complexation half of the dyes, and sodium hydroxide move into alkaline, drying. The component of product is about 2 to 3 Moore single atoms chromium azo dyes.
Properties and Applications
black. Dark brown powder. A red light black soluble in water, soluble in ethanol and soluble fiber element, slightly soluble in acetone, insoluble in other organic solvents. Meet strong sulfuric acid is dark, dilute to create black precipitation; Meet nitric acid was yellow brown solution; In a rare dark-purple sodium hydroxide solution. Used for wool, polyamide, silk dyeing and printing, also used in leather and electrochemical dyeing aluminum shading.

Check Digit Verification of cas no
The CAS Registry Mumber 5610-64-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,1 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5610-64:
(6*5)+(5*6)+(4*1)+(3*0)+(2*6)+(1*4)=80
80 % 10 = 0
So 5610-64-0 is a valid CAS Registry Number.
