General Description
The chemical "(7alpha,17beta)-17-(Acetyloxy)-7-(9-bromononyl)estr-4-en-3-one" is a synthetic organic compound that belongs to the class of steroids. It is a derivative of estrone, a naturally occurring hormone in the human body. The chemical has a substitution of an acetyloxy group at the 17th carbon position and a bromononyl group at the 7th carbon position. This modification alters the biological activity and pharmacokinetic properties of the compound. It may have potential applications in research and drug development related to hormonal disorders and reproductive health.
Check Digit Verification of cas no
The CAS Registry Mumber 875573-63-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,5,5,7 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 875573-63:
(8*8)+(7*7)+(6*5)+(5*5)+(4*7)+(3*3)+(2*6)+(1*3)=220
220 % 10 = 0
So 875573-63-0 is a valid CAS Registry Number.

Paragraph 0047-0049, (2020/09/23)
The invention belongs to the field of pharmaceutical chemicals, and relates to a fulvestrant impurity control method, which is characterized in that from the introduction of chiral carbon to the synthesis of a fulvestrant intermediate compound represented by a formula VII-1, multi-step and step-by-step control is performed on 7beta isomer impurities, so that the 7beta isomer content of the VII-1 compound is between 0.1% and 0.3%, and finally the qualified fulvestrant bulk drug with stable quality is prepared. The impurity control method is simple to operate, low in production cost and high intotal yield, and can be applied to large-scale industrial production.
