4702-64-1 Usage
General Description
4,8-diamino-1,5-dihydroxy-2-(4-methoxyphenyl)anthraquinone, also known as Disperse Blue 56, is a synthetic dye used in the textile and paper industries to impart a blue color to the products. It is classified as an anthraquinone derivative and is insoluble in water, but soluble in organic solvents. The chemical is known for its stability and resistance to fading, making it a popular choice for dyeing synthetic fibers. However, there are concerns about its potential impact on human health and the environment, as some studies have linked it to skin and eye irritation, as well as toxicity to aquatic organisms. As a result, there is ongoing research and regulations regarding its use and disposal.
Check Digit Verification of cas no
The CAS Registry Mumber 4702-64-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4702-64:
(6*4)+(5*7)+(4*0)+(3*2)+(2*6)+(1*4)=81
81 % 10 = 1
So 4702-64-1 is a valid CAS Registry Number.
