3-[(2,4-dihydroxyphenyl)azo]naphthalene-1,5-disulphonic acid is a complex organic compound with the chemical formula C16H12N2O7S2. It is a type of azo dye, characterized by the presence of an azo group (-N=N-) connecting two aromatic rings. This particular compound features a naphthalene ring (a fused pair of benzene rings) at one end and a phenyl ring (a single benzene ring) at the other, with the azo group in between. The phenyl ring is substituted with two hydroxyl groups at the 2 and 4 positions, and the naphthalene ring is further functionalized with two sulfonic acid groups at the 1 and 5 positions. These sulfonic acid groups confer water solubility and acidic properties to the molecule. 3-[(2,4-dihydroxyphenyl)azo]naphthalene-1,5-disulphonic acid is significant in the field of dye chemistry, particularly for its potential applications in the synthesis of pigments and other colorants due to its ability to form stable, colored complexes.

4317-65-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4317-65-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,1 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.Calculate Digit Verification of CAS Registry Number 4317-65:
(6*4)+(5*3)+(4*1)+(3*7)+(2*6)+(1*5)=81
81 % 10 = 1
So 4317-65-1 is a valid CAS Registry Number.
