Uses
Used in Pharmaceutical Industry:
3β-Hydroxy-5,7,9-estratrien-17-one is used as a key reagent for the synthesis of 17α-derivatives of Estradiol (E888000). Estradiol, a biologically potent sex hormone, is naturally synthesized in the body and plays a vital role in the regulation of the menstrual cycle, maintenance of pregnancy, and development of secondary sex characteristics. Additionally, it is used in hormone replacement therapy and as a component in various contraceptive formulations.
Furthermore, Estradiol is suspected to be a factor in the progression of breast cancer in women, making 3β-Hydroxy-5,7,9-estratrien-17-one an essential compound in the development of targeted therapies and potential treatments for this type of cancer.
Check Digit Verification of cas no
The CAS Registry Mumber 567-12-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 567-12:
(5*5)+(4*6)+(3*7)+(2*1)+(1*2)=74
74 % 10 = 4
So 567-12-4 is a valid CAS Registry Number.
