3-[(5-chloro-2-hydroxyphenyl)hydrazono]-5-hydroxy-4-oxo-3,4-dihydronaphthalene-2,7-disulfonic acid is a complex organic compound with the molecular formula C16H11ClN2O8S2. It is characterized by a naphthalene core with a 3,4-dihydronaphthalene structure, which means it has a double bond between carbons 3 and 4, reducing the aromaticity. The molecule features a 5-hydroxy group, indicating the presence of a hydroxyl group at the 5th carbon position. Additionally, it has a 4-oxo group, signifying a carbonyl group at the 4th carbon. The compound is further adorned with two sulfonic acid groups at the 2nd and 7th positions, which contribute to its acidity and water solubility. The hydrazone functional group is formed by the reaction of a hydrazine with the 5-chloro-2-hydroxyphenyl moiety, creating a bond between the nitrogen of the hydrazine and the carbonyl carbon of the phenyl group. 3-[(5-chloro-2-hydroxyphenyl)hydrazono]-5-hydroxy-4-oxo-3,4-dihydronaphthalene-2,7-disulfonic acid is likely to be used in chemical research or as an intermediate in the synthesis of pharmaceuticals or dyes, given its complex structure and functional groups.

7361-97-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7361-97-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,6 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7361-97:
(6*7)+(5*3)+(4*6)+(3*1)+(2*9)+(1*7)=109
109 % 10 = 9
So 7361-97-9 is a valid CAS Registry Number.
