4-(acetylamino)-5-hydroxynaphthalene-1,7-disulphonic acid is a complex organic chemical compound with the molecular formula C12H11NO7S2. It is characterized by a naphthalene ring structure, which is a fused ring system consisting of two benzene rings. The compound features an acetylamino group (-NHCOCH3) attached to the 4-position of the naphthalene, a hydroxyl group (-OH) at the 5-position, and two sulfonic acid groups (-SO3H) at the 1 and 7 positions. These functional groups confer unique properties to the molecule, such as solubility in water due to the sulfonic acid groups and potential reactivity due to the acetylamino and hydroxyl groups. 4-(acetylamino)-5-hydroxynaphthalene-1,7-disulphonic acid may be used in various chemical processes or as an intermediate in the synthesis of other compounds, particularly in the pharmaceutical or dye industries, where its specific functional groups can be further modified or utilized in reactions.

6409-21-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6409-21-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6409-21:
(6*6)+(5*4)+(4*0)+(3*9)+(2*2)+(1*1)=88
88 % 10 = 8
So 6409-21-8 is a valid CAS Registry Number.
