3-Ethoxy-17β-hydroxy-1,3,5(10)-estratriene is a synthetic estrogen compound, which is a derivative of the naturally occurring hormone estradiol. This chemical is characterized by the presence of an ethoxy group at the 3-position and a hydroxyl group at the 17β-position, with a tricyclic structure consisting of three fused rings (A, B, and C). It exhibits estrogenic activity, which means it can mimic the effects of the female sex hormone estrogen in the body. 3-ethoxy-17β-hydroxy-1,3,5(10)-estratriene is used in pharmaceutical applications, particularly in hormone replacement therapy and contraceptive formulations, due to its ability to bind to and activate estrogen receptors. The chemical's structure allows for targeted effects, and its synthetic nature enables controlled production and dosage.

Check Digit Verification of cas no

The CAS Registry Mumber 3494-09-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,9 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3494-09:
(6*3)+(5*4)+(4*9)+(3*4)+(2*0)+(1*9)=95
95 % 10 = 5
So 3494-09-5 is a valid CAS Registry Number.
