21513-89-3 Usage

General Description

1-[(17beta)-estra-3,5-dien-17-yl]ethanone, also known as 17β-estradiol or E2, is a naturally occurring steroid hormone and the primary female sex hormone. It is produced primarily by the ovaries and is involved in the regulation of the menstrual cycle, development of secondary sexual characteristics, and maintenance of pregnancy. E2 plays a crucial role in bone health, cardiovascular function, and cognitive function. It is also used as a medication, primarily in hormone replacement therapy for menopausal symptoms and to treat certain types of breast cancer. E2 is a potent estrogen and exerts its effects by binding to and activating estrogen receptors in various tissues throughout the body.

Check Digit Verification of cas no

The CAS Registry Mumber 21513-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,1 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21513-89:
(7*2)+(6*1)+(5*5)+(4*1)+(3*3)+(2*8)+(1*9)=83
83 % 10 = 3
So 21513-89-3 is a valid CAS Registry Number.
