7-Amino-3-[[4-[(4-chloro-2-sodiosulfophenyl)azo]-3-methylphenyl]azo]-4-hydroxynaphthalene-2-sulfonic acid sodium salt is a complex organic compound with the molecular formula C24H16ClN5NaO5S2. It is a type of azo dye, characterized by the presence of azo groups (-N=N-) in its structure. 7-Amino-3-[[4-[(4-chloro-2-sodiosulfophenyl)azo]-3-methylphenyl]azo]-4-hydroxynaphthalene-2-sulfonic acid sodium salt is anionic, as indicated by the presence of the sodium salt, which means it carries a negative charge. It is likely used in applications where coloration is required, such as in the dyeing of fabrics or as a pigment in various industrial processes. The specific structure, with a 4-hydroxynaphthalene core and a sulfonic acid group, suggests that it may have solubility properties in water, which is a common characteristic of many dyestuffs. The presence of a chlorine atom and a methyl group on the phenyl ring, along with the sodium sulfonate group, contributes to its chemical reactivity and stability in various environments.

Check Digit Verification of cas no

The CAS Registry Mumber 6226-97-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,2 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6226-97:
(6*6)+(5*2)+(4*2)+(3*6)+(2*9)+(1*7)=97
97 % 10 = 7
So 6226-97-7 is a valid CAS Registry Number.
