6407-99-4 Usage
Preparation
5-Chloro-2-methoxybenzenamine diazo, and 7-Hydroxynaphthalene-1,3-disulfonic acid coupling, and then in water solution and formic acid chromium common heating, in 120 ~ 135 ℃ to keep four or more hours, make its formed chromium complex. In contain chromium acid alkali type dry for, in chrome complexation processes medium armor oxygen radicals for hydroxyl displacement.
Properties and Applications
dark purple. Deep purple powder. Soluble in water (purple) and ethanol, slightly soluble in soluble fiber element. In strong sulfuric acid are blue-ray red, it will be diluted red to a purple; In 10% of sodium hydroxide solution is red. Used for wool, silk and polyamide fiber dyeing and printing and direct discharge printing, also used in leather and electrochemical aluminum shading. Especially suitable for wool carpet and influential product of dyeing.

Check Digit Verification of cas no
The CAS Registry Mumber 6407-99-4 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 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6407-99:
(6*6)+(5*4)+(4*0)+(3*7)+(2*9)+(1*9)=104
104 % 10 = 4
So 6407-99-4 is a valid CAS Registry Number.
