Description
Used in Pharmaceutical Industry:(17beta)-17-ethenyl-17-hydroxyestr-5(10)-en-3-one (17beta)-17-ethynylestra-1,3,5(10)-triene-3,17-diol (1:1) is used as an oral contraceptive for preventing pregnancy. The combination of ethinylestradiol and norethindrone works synergistically to prevent ovulation, alter cervical mucus and uterine lining, making it difficult for sperm to reach the uterus and for a fertilized egg to attach to the uterus.
Check Digit Verification of cas no
The CAS Registry Mumber 8064-75-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,6 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.Calculate Digit Verification of CAS Registry Number 8064-75:
(6*8)+(5*0)+(4*6)+(3*4)+(2*7)+(1*5)=103
103 % 10 = 3
So 8064-75-3 is a valid CAS Registry Number.
