The chemical compound "3-((8R,9S,13S,14S)-13-Methyl-17-oxo-7,8,9,11,12,13,14,15,16,17-decahydro-6H-cyclopenta[a]phenanthren-3-yl)-2-phenyl-3H-quinazolin-4-one" is a complex organic molecule with a molecular formula of C33H31NO3. It features a quinazolinone core, which is a heterocyclic compound with a fused benzene ring and a pyrimidine ring. The compound is characterized by its specific stereochemistry, with the 8R, 9S, 13S, and 14S configurations indicating the three-dimensional arrangement of atoms around the asymmetric carbon centers. The molecule also includes a cyclopenta[a]phenanthren-3-yl group, which is a polycyclic aromatic hydrocarbon with a decalin (a bicyclo[4.4.0]decane) structure, and a phenyl group attached to the quinazolinone core. 3-((8R,9S,13S,14S)-13-Methyl-17-oxo-7,8,9,11,12,13,14,15,16,17-decahydro-6H-cyclopenta[a]phenanthren-3-yl)-2-phenyl-3H-quinazolin-4-one is likely to be found in the field of medicinal chemistry, potentially as a precursor or intermediate in the synthesis of pharmaceuticals, given its complex structure and the presence of a quinazolinone ring, which is a common structural motif in many bioactive molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 5295-55-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,9 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5295-55:
(6*5)+(5*2)+(4*9)+(3*5)+(2*5)+(1*5)=106
106 % 10 = 6
So 5295-55-6 is a valid CAS Registry Number.

New efficient pathway for the synthesis of 3-aminoestrone

Radu, Ioan-Iosif,Poirier, Donald,Provencher, Louis

, p. 7617 - 7619 (2007/10/03)

3-Aminoestrone, a non-natural C-18 steroid, was synthesized by the classical and by a new efficient pathway, the latter using benzophenone imine as an ammonia equivalent in the palladium(0)-catalysed amination of estrone-triflate. This methodology circumv
