16,16-Difluoro-3-methoxyestra-1,3,5(10)-trien-17-one is a synthetic steroid compound derived from the naturally occurring hormone estrogen. It features a unique structure with two fluorine atoms at the 16th carbon position and a methoxy group at the 3rd carbon position. This chemical modification results in enhanced binding affinity to the estrogen receptor, which can lead to increased potency compared to natural estrogens. The compound is of interest in medical research for its potential therapeutic applications, particularly in the treatment of conditions related to hormone imbalances. However, it is important to note that the safety and efficacy of 16,16-Difluoro-3-methoxyestra-1,3,5(10)-trien-17-one in humans have not been fully established, and it is not approved for medical use. Further research is required to understand its full potential and any associated risks.
The CAS Registry Mumber 2991-05-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,9 and 1 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 2991-05: (6*2)+(5*9)+(4*9)+(3*1)+(2*0)+(1*5)=101 101 % 10 = 1 So 2991-05-1 is a valid CAS Registry Number.
