2-Naphthalenesulfonic acid, 8-[(7-amino-1-hydroxy-3-sulfo-2-naphthalenyl)azo]-5-[[4-(phenylazo)-6-sulfo-1-naphthalenyl]azo]-, trisodium salt is a complex organic compound with the chemical formula C34H22N6Na3O9S3. It is a type of azo dye, characterized by the presence of azo groups (-N=N-) and multiple sulfonic acid groups. This particular compound is a trisodium salt, meaning it contains three sodium ions (Na+) that balance the negative charges from the sulfonic acid groups. It is derived from naphthalene, a polycyclic aromatic hydrocarbon, and features a complex structure with multiple aromatic rings and functional groups. 2-Naphthalenesulfonic acid, 8-[(7-amino-1-hydroxy-3-sulfo- 2-naphthalenyl)azo]-5-[[4-(phenylazo)-6-sulfo -1-naphthalenyl]azo]-, trisodium salt is used as a dye in various applications due to its ability to impart color to materials.

6476-10-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6476-10-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,7 and 6 respectively; the second part has 2 digits, 1 and 0 respectively.Calculate Digit Verification of CAS Registry Number 6476-10:
(6*6)+(5*4)+(4*7)+(3*6)+(2*1)+(1*0)=104
104 % 10 = 4
So 6476-10-4 is a valid CAS Registry Number.
