14340-04-6 Usage
General Description
17α-Acetoxy-19-norpregna-4,9-diene-3,20-dione, also known as norethindrone acetate, is a synthetic progestin and a derivative of the naturally occurring hormone progesterone. It is commonly used in hormonal contraceptive medications, such as birth control pills and hormone replacement therapy. Norethindrone acetate works by interfering with the normal menstrual cycle and preventing ovulation. Additionally, it can also alter the cervical mucus and the uterine lining, making it difficult for sperm to reach the egg and for a fertilized egg to implant itself in the uterus. This chemical compound has also been used in the treatment of irregular menstrual cycles, endometriosis, and as a component in menopausal hormone therapy.
Check Digit Verification of cas no
The CAS Registry Mumber 14340-04-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,3,4 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 14340-04:
(7*1)+(6*4)+(5*3)+(4*4)+(3*0)+(2*0)+(1*4)=66
66 % 10 = 6
So 14340-04-6 is a valid CAS Registry Number.
