7-hydroxy-9,10-dioxo-9,10-dihydro-anthracene-2-sulfonic acid is a complex organic compound with the molecular formula C14H10O5S. It is a derivative of anthracene, a tricyclic aromatic hydrocarbon, and features a hydroxyl group at the 7th carbon, a sulfonic acid group at the 2nd carbon, and two carbonyl groups at the 9th and 10th carbons. 7-hydroxy-9,10-dioxo-9,10-dihydro-anthracene-2-sulfonic acid is characterized by its unique structure, which includes a partially reduced anthracene ring system with a dihydro configuration, and a dioxo group that contributes to its reactivity and potential applications in various chemical processes. The presence of the sulfonic acid group also imparts water-solubility and acidic properties, which can be exploited in the synthesis of dyes, pharmaceuticals, and other specialty chemicals.
The CAS Registry Mumber 1157-08-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,5 and 7 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1157-08: (6*1)+(5*1)+(4*5)+(3*7)+(2*0)+(1*8)=60 60 % 10 = 0 So 1157-08-0 is a valid CAS Registry Number.
