Preparation
1-Amino-4-bromo-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid and 2,4,6-Trimethylbenzenamine?condensation, and then to 4-Tert-Octylphenol?and second condensation, and hair smoke sulphonated sulfuric acid.Properties and Applications
the appearance of the Dark reddish brown powder, soluble point 100 ℃, λ Max = 592 nm (water), soluble in water, in 20 ℃ water solubility of 8 g/L. In strong hydrochloric acid for product red, diluted into light purple, have precipitation; In nitric acid for coffee. Its water solution for product red, add hydrochloric acid for sauce and after red precipitate; After add sodium hydroxide and have better light precipitation. Levelness medium, white sex is not good. Used for wool, silk, polyamide fiber and its blended fabric dyeing and printing, but also can be used for leather color.

6Check Digit Verification of cas no
The CAS Registry Mumber 12220-51-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,2 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.Calculate Digit Verification of CAS Registry Number 12220-51:
(7*1)+(6*2)+(5*2)+(4*2)+(3*0)+(2*5)+(1*1)=48
48 % 10 = 8
So 12220-51-8 is a valid CAS Registry Number.
