Description
Reactive Violet 2 is a grey purple powder that exhibits red light purple color. It undergoes color changes when treated with different chemicals, such as turning blue-black with strong sulfuric acid, brown in nitric acid, and red purple in water solution. It is a reactive dye used for dyeing and printing on various fibers.Uses
Used in Textile Industry:Reactive Violet 2 is used as a dye and printing agent for cotton or viscose fibers, as well as for wool and silk fibers. It provides good light fastness, oxygen bleaching resistance, perspiration fastness, and soaping resistance, making it suitable for various textile applications.

6Check Digit Verification of cas no
The CAS Registry Mumber 8063-57-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,6 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.Calculate Digit Verification of CAS Registry Number 8063-57:
(6*8)+(5*0)+(4*6)+(3*3)+(2*5)+(1*7)=98
98 % 10 = 8
So 8063-57-8 is a valid CAS Registry Number.
