1169-79-5 Usage
General Description
Quinestradol is a synthetic estrogen that belongs to the family of estradiol derivatives. It is commonly used as a key ingredient in hormone replacement therapy to alleviate symptoms of menopause, such as hot flashes, vaginal dryness, and mood swings. Quinestradol works by mimicking the natural estrogen hormone in the body, thereby providing relief from the symptoms associated with estrogen deficiency. However, it is important to use quinestradol under the guidance of a healthcare professional as it may have potential side effects and risks, especially when used in combination with other medications. Overall, quinestradol plays a crucial role in managing menopausal symptoms and improving the quality of life for women experiencing estrogen deficiency.
Check Digit Verification of cas no
The CAS Registry Mumber 1169-79-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,6 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1169-79:
(6*1)+(5*1)+(4*6)+(3*9)+(2*7)+(1*9)=85
85 % 10 = 5
So 1169-79-5 is a valid CAS Registry Number.

The conventional etherification uses toxic or hardly degradable alkylating agents. An eco-friendly tandem etherification/aromatization is presented to prepare estrone 3-secondary ethers from easily available dienone 1. Three marketed 3-etherified estrogen drugs were synthesized with the method from commercial available starting material.
