4-(1,1-dimethyl-2-phenyl-ethyl)-2-phenyl-isoxazolidine-3,5-dione is a complex organic compound with the molecular formula C20H21NO2. It is a derivative of isoxazolidine, a heterocyclic compound containing an isoxazole ring fused to an oxazolidine ring. This specific compound features a 1,1-dimethyl-2-phenyl-ethyl group attached to the 4-position of the isoxazolidine ring, and a phenyl group at the 2-position. The 3,5-dione functional group indicates the presence of two carbonyl groups at these positions. This chemical is known for its potential applications in pharmaceuticals and as a chiral auxiliary in asymmetric synthesis, due to its unique structure and properties.
The CAS Registry Mumber 5305-15-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,0 and 5 respectively; the second part has 2 digits, 1 and 5 respectively. Calculate Digit Verification of CAS Registry Number 5305-15: (6*5)+(5*3)+(4*0)+(3*5)+(2*1)+(1*5)=67 67 % 10 = 7 So 5305-15-7 is a valid CAS Registry Number.
