3,7β-dihydroxy-estra-1,3,5(10)-trien-17-one, also known as equilenin, is a naturally occurring steroidal compound belonging to the class of equine estrogens. It is structurally similar to the human estrogen 17β-estradiol but possesses a unique 3-hydroxyl group and a 7β-hydroxyl group. Equilenin is primarily found in the urine of pregnant mares and is used in the pharmaceutical industry for the production of various estrogenic drugs. It exhibits potent estrogenic activity and has been implicated in the treatment of various hormonal imbalances and conditions, such as menopausal symptoms and osteoporosis. However, due to its potential side effects and risks, including increased risk of blood clots and endometrial cancer, its use is carefully monitored and regulated.
The CAS Registry Mumber 2487-47-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,8 and 7 respectively; the second part has 2 digits, 4 and 7 respectively. Calculate Digit Verification of CAS Registry Number 2487-47: (6*2)+(5*4)+(4*8)+(3*7)+(2*4)+(1*7)=100 100 % 10 = 0 So 2487-47-0 is a valid CAS Registry Number.
