5-(2-acetylamino-phenylsulfanyl)-4-chloro-2-phenyl-2H-pyridazin-3-one is a complex organic compound with a molecular formula of C20H15ClN2O3S. It features a pyridazinone core, which is a heterocyclic ring system consisting of a pyridine ring fused to a diazine ring. The compound has a 4-chloro substituent, indicating the presence of a chlorine atom at the 4-position of the pyridazine ring. Additionally, it has a 2-phenyl group, which is a benzene ring attached at the 2-position, and a 5-(2-acetylamino-phenylsulfanyl) group, which includes a sulfanyl (sulfur-hydrogen) linkage to a phenyl ring that is further substituted with an acetylamino group. This acetylamino group consists of an acetyl (two-carbon) amide linked to an amino group. The compound's structure and properties make it potentially useful in various chemical and pharmaceutical applications, though specific uses would depend on its reactivity, stability, and biological activity.
The CAS Registry Mumber 2167-70-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 7 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 2167-70: (6*2)+(5*1)+(4*6)+(3*7)+(2*7)+(1*0)=76 76 % 10 = 6 So 2167-70-6 is a valid CAS Registry Number.
