(9β)-17β-Hydroxyestr-4-en-3-one, also known as 17β-estradiol, is a naturally occurring steroid hormone and the primary female sex hormone. It plays a crucial role in the development of female sexual characteristics, regulation of the menstrual cycle, and maintenance of pregnancy. Structurally, it is a derivative of estrane with a hydroxy group at the 17β position and a ketone group at the 3 position. This hormone is synthesized in the ovaries, adrenal glands, and placenta, and it is involved in various physiological processes, including bone health, cardiovascular function, and cognitive function. The chemical's molecular formula is C18H24O2, and it is an essential component in the treatment of various conditions related to estrogen deficiency, such as menopause and osteoporosis.

4374-03-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4374-03-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,7 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.Calculate Digit Verification of CAS Registry Number 4374-03:
(6*4)+(5*3)+(4*7)+(3*4)+(2*0)+(1*3)=82
82 % 10 = 2
So 4374-03-2 is a valid CAS Registry Number.
