The chemical compound "3,9α,17β-trihydroxyestra-1,3,5(10)-trien-11-one 17-acetate 3-methyl ether" is a complex organic molecule belonging to the class of steroids, specifically a derivative of estrone. It features three hydroxyl groups at the 3, 9α, and 17β positions, an 11-ketone group, and a 17-acetate esterification, which contributes to its lipophilic nature. The 3-methyl ether group indicates that a methyl group is attached to the oxygen atom at the 3 position, potentially influencing the compound's reactivity and solubility. This molecule is significant in the field of pharmaceuticals and endocrinology, as it is related to natural estrogens and may have applications in hormone therapy or as a research tool in studying steroidal compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 1923-05-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,2 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1923-05:
(6*1)+(5*9)+(4*2)+(3*3)+(2*0)+(1*5)=73
73 % 10 = 3
So 1923-05-3 is a valid CAS Registry Number.
