"3β-acetoxy-2',3'ξ-diphenyl-(16β)-dihydro-pregn-5-eno[16,17-d]isoxazol-20-one" is a complex organic compound with a unique molecular structure. It is characterized by the presence of a pregnane core, which is a type of steroid, and an isoxazole ring fused to the steroid framework. The molecule also features a dihydro group at the 16β position and a 5-eno double bond, indicating a reduced and unsaturated steroid structure. The 3β position is acetylated, and the molecule has two phenyl groups attached at the 2' and 3' positions, which are part of a larger diphenyl group. 3β-acetoxy-2',3'ξ-diphenyl-(16β)-dihydro-pregn-5-eno[16,17-d]isoxazol-20-one is likely to be of interest in the field of medicinal chemistry, potentially for its hormonal or pharmacological properties, given the presence of the pregnane skeleton, which is common in many biologically active steroids.
The CAS Registry Mumber 1110-66-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,1 and 0 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 1110-66: (6*1)+(5*1)+(4*1)+(3*0)+(2*6)+(1*6)=33 33 % 10 = 3 So 1110-66-3 is a valid CAS Registry Number.
