4-phenyl-2-p-tolyl-[1,2,4]oxadiazolidine-3,5-dione is a complex organic compound with the molecular formula C17H14N2O2. It is characterized by a 1,2,4-oxadiazolidine ring, which is a five-membered heterocyclic ring containing two nitrogen atoms and one oxygen atom. The compound features a phenyl group (C6H5) attached to the 4-position and a p-tolyl group (a methyl-substituted phenyl group) attached to the 2-position of the oxadiazolidine ring. The 3,5-dione part of the name indicates the presence of two carbonyl groups (C=O) at these positions. 4-phenyl-2-p-tolyl-[1,2,4]oxadiazolidine-3,5-dione is likely to be used in the synthesis of pharmaceuticals or other organic compounds due to its unique structure and potential reactivity.
The CAS Registry Mumber 1660-61-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,6 and 0 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1660-61: (6*1)+(5*6)+(4*6)+(3*0)+(2*6)+(1*1)=73 73 % 10 = 3 So 1660-61-3 is a valid CAS Registry Number.
