Estrone 3-cyclopentyl ether is a synthetic chemical compound with the molecular formula C22H32O2. It is a derivative of estrone, a naturally occurring estrogen hormone, and is characterized by the presence of a cyclopentyl group attached to the 3-position of the estrone molecule. This modification is intended to alter the pharmacological properties of the parent compound, potentially enhancing its stability, bioavailability, or targeting specific receptors. The compound is of interest in pharmaceutical research, particularly in the development of drugs for hormone-related conditions. It is important to note that the safety, efficacy, and specific applications of estrone 3-cyclopentyl ether are subject to ongoing scientific investigation and may not be fully established.
The CAS Registry Mumber 1852-81-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,5 and 2 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1852-81: (6*1)+(5*8)+(4*5)+(3*2)+(2*8)+(1*1)=89 89 % 10 = 9 So 1852-81-9 is a valid CAS Registry Number.
