It is a derivative of cyclopenta[5,6]naphtho[1,2-d]azepine, containing a ketone group and a hydroxylamine group. The compound is a 8-oxime, indicating the presence of a functional group formed from the reaction of a oxime to the eighth carbon of the molecule. Its molecular formula is C18H23NO2, and it may have potential applications in medicinal chemistry and pharmacology due to its unique structure and properties.
Check Digit Verification of cas no
The CAS Registry Mumber 21058-62-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,5 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21058-62:
(7*2)+(6*1)+(5*0)+(4*5)+(3*8)+(2*6)+(1*2)=78
78 % 10 = 8
So 21058-62-8 is a valid CAS Registry Number.

Beckmann rearrangement of 3-aza-A-homo-4α-androsten-4,17-dione oxime and 3-oxo-13α-amino-13,17-seco-4-androsten-17-oic 13,17-lactam oxime

Rearragements of 3-aza-A-homo-4α-androsten-4,17-dione oxime produced a mixture of the normal lactam product and the product of a 'second order' cleavage, an unsaturated nitrile. The lactam 3,17α-diaza-A,D-bishomoandrost-4α-ene-4,17-dione was also obtained from the rearrangement of the syn-3-oxo-13α-amino-13,17-seco-4-androsten-17-oic-13,17-lactam oxime. The resolution of syn- and anti-isomers of VIII was effected by column chromatography and their structure was determined by spectral data.
