7-Amino-4-hydroxy-3-[[4-[(2,4-dimethyl-5-sodiosulfophenyl)azo]-5-methyl-2-methoxyphenyl]azo]naphthalene-2-sulfonic acid sodium salt is a complex organic compound with the chemical formula C28H24N4NaO7S2. It is a type of azo dye, characterized by the presence of azo groups (-N=N-) in its structure. This particular compound is a sodium salt, indicating that it has a sodium ion (Na+) associated with it. It is derived from naphthalene, a polycyclic aromatic hydrocarbon, and features various functional groups such as amino, hydroxy, and sulfonic acid groups, as well as methyl and methoxy substituents. The compound's structure is further diversified by the presence of a sulfonated phenyl ring and a dimethylsulfophenyl group, which contribute to its overall properties and potential applications. This chemical is primarily used in the dyeing industry, particularly for coloring textiles and other materials, due to its ability to form strong and stable colorations.

Check Digit Verification of cas no

The CAS Registry Mumber 6226-98-8 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 8 respectively.
Calculate Digit Verification of CAS Registry Number 6226-98:
(6*6)+(5*2)+(4*2)+(3*6)+(2*9)+(1*8)=98
98 % 10 = 8
So 6226-98-8 is a valid CAS Registry Number.
