General Description

5-amino-4-hydroxy-3-[[2-methoxy-5-methyl-4-[[8-[(phenylsulphonyl)oxy]-3,6-disulpho-1-naphthyl]azo]phenyl]azo]naphthalene-2,7-disulphonic acid, commonly known as Acid Red 52, is a complex organic compound with a bright red color. It is commonly used as a dye in various industries, including textiles, food, and cosmetics. 5-amino-4-hydroxy-3-[[2-methoxy-5-methyl-4-[[8-[(phenylsulphonyl)oxy]-3,6-disulpho-1-naphthyl]azo]phenyl]azo]naphthalene-2,7-disulphonic acid is composed of multiple azo groups, sulfonic acid groups, and other functional groups, giving it strong coloring properties and water solubility. However, due to its complex chemical structure, Acid Red 52 has been under scrutiny for its potential environmental and health impacts, with concerns about its persistence, bioaccumulation, and toxicity. Nonetheless, it remains a widely used dye in many applications.

Check Digit Verification of cas no

The CAS Registry Mumber 117-45-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117-45:
(5*1)+(4*1)+(3*7)+(2*4)+(1*5)=43
43 % 10 = 3
So 117-45-3 is a valid CAS Registry Number.
