4-(4-chloro-phenyl)-3-p-tolyl-3H-[1,2,3,5]oxathiadiazole 2-oxide is a complex organic compound with the molecular formula C16H12ClNOS2. It is characterized by a 1,2,3,5-oxathiadiazole ring system, which is a heterocyclic structure containing sulfur and oxygen atoms. The compound features a 4-chlorophenyl group attached to the 4-position of the oxathiadiazole ring and a p-tolyl group (a phenyl group with a methyl substituent at the para position) at the 3-position. The 2-oxide functional group indicates the presence of an oxygen atom at the 2-position of the oxathiadiazole ring, which contributes to the compound's reactivity and properties. This chemical is typically synthesized for use in pharmaceuticals or as a precursor in the synthesis of other complex molecules, given its unique structure and potential for further functionalization.
The CAS Registry Mumber 3815-56-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,1 and 5 respectively; the second part has 2 digits, 5 and 6 respectively. Calculate Digit Verification of CAS Registry Number 3815-56: (6*3)+(5*8)+(4*1)+(3*5)+(2*5)+(1*6)=93 93 % 10 = 3 So 3815-56-3 is a valid CAS Registry Number.
