Braxorone is a hypothetical chemical compound, and as such, there is no real-world data or scientific information available about it. In a fictional context, Braxorone could be imagined as a powerful, innovative substance with unique properties and applications. It might be portrayed as a breakthrough in pharmaceuticals, capable of treating a wide range of diseases, or as a cutting-edge material with extraordinary capabilities in various industries. However, without specific details or a defined context, any summary of Braxorone would be purely speculative and based on creative imagination.

Check Digit Verification of cas no

The CAS Registry Mumber 2527-11-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,2 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2527-11:
(6*2)+(5*5)+(4*2)+(3*7)+(2*1)+(1*1)=69
69 % 10 = 9
So 2527-11-9 is a valid CAS Registry Number.

A Stereoselective Total Synthesis of 11-Oxoprogesterone, a Precursor to the Corticosteroids, via an Intramolecular Cycloaddition Reaction

Nemoto, Hideo,Nagai, Mitsuo,Fukumoto, Keiichiro,Kametani, Tetsuji

, p. 1621 - 1626 (2007/10/02)

A stereoselective synthesis of 11-oxoprogesterone (pregn-4-ene-3,11,20-trione) (21) has been achieved via 19-norpregna-4,9(10)-diene-3,20-dione (14) and pregna-4,9(10)-diene-3,20-dione (18).The compound (14) was derived from the des-A,B-aromatic steroid (6), which was, in turn, constructed in a stereoselective manner via (3) by the thermolysis of the olefinic benzocyclobutene (2).
