3-Ethoxy-estra-3,5(10),9(11)-trien-17-one is a synthetic steroidal compound that belongs to the class of estranes. It is characterized by the presence of a 17-ketone group and an ethoxy group at the 3-position. This molecule features a tricyclic structure with a cyclopentane ring fused to two cyclohexane rings, and it has three double bonds at positions 3, 5(10), and 9(11). The compound is derived from the estrane skeleton, which is a common structural motif in natural and synthetic estrogens. Due to its unique structure, it may exhibit biological activities similar to those of natural estrogens, making it a potential candidate for pharmaceutical applications, particularly in the development of hormone therapies. However, further research is needed to understand its full range of effects and potential applications.

Check Digit Verification of cas no

The CAS Registry Mumber 5190-40-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,9 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5190-40:
(6*5)+(5*1)+(4*9)+(3*0)+(2*4)+(1*0)=79
79 % 10 = 9
So 5190-40-9 is a valid CAS Registry Number.
