Δ1,3,5(10)-Oestratriendiol-(2,17β)-diacetat, also known as 17β-dihydroxyestra-1,3,5(10)-trien-2-yl diacetate, is a synthetic derivative of the naturally occurring steroid hormone estradiol. Δ1,3,5(10)-Oestratriendiol-(2,17β)-diacetat is characterized by the presence of three hydroxyl groups at the 1, 3, and 5(10) positions, and two acetate groups at the 2 and 17β positions. It is used in pharmaceutical applications, particularly in the development of drugs targeting estrogen receptors, which play a crucial role in the regulation of the menstrual cycle, pregnancy, and other physiological processes. The acetate groups in Δ1,3,5(10)-Oestratriendiol-(2,17β)-diacetat are likely added to improve its stability and bioavailability, making it a potentially valuable compound in the field of endocrinology and women's health.
The CAS Registry Mumber 17519-71-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,1 and 9 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 17519-71: (7*1)+(6*7)+(5*5)+(4*1)+(3*9)+(2*7)+(1*1)=120 120 % 10 = 0 So 17519-71-0 is a valid CAS Registry Number.
