17α-Ethynylandrosta-4,6-dien-17β-ol-3-one, also known as ethisterone or 17α-ethynylestradiol, is a synthetic steroid hormone with both estrogenic and progestogenic properties. It is a derivative of the naturally occurring hormone estradiol, with an added 17α-ethynyl group, which enhances its oral bioavailability and potency. Ethisterone is primarily used in the treatment of various hormonal imbalances, such as amenorrhea, dysfunctional uterine bleeding, and endometriosis. It is also used as a component in some combined oral contraceptives to regulate menstrual cycles and prevent pregnancy. Due to its potent effects, it is essential to use ethisterone under the supervision of a healthcare professional to minimize potential side effects and ensure its safe and effective use.

Calculate Digit Verification of CAS Registry Number 2668-77:
(6*2)+(5*6)+(4*6)+(3*8)+(2*7)+(1*7)=111
111 % 10 = 1
