(1R,2R,6R,7R)-3-Oxo-5,6-diphenyl-2,4-dipropyl-8-aza-tricyclo[5.3.2.0^2,6^]dodeca-4,9,11-triene-8-carboxylic acid ethyl ester is a complex organic compound with a molecular formula of C30H33NO3. It is a derivative of a tricyclic ring system, featuring a central nitrogen atom that imparts aza characteristics to the molecule. The structure includes two phenyl groups at positions 5 and 6, and two propyl groups at positions 2 and 4, which contribute to its steric hindrance and shape. The molecule also contains a carbonyl group at position 3, indicating the presence of a ketone, and an ester group derived from ethyl alcohol, which is attached to the carboxylic acid at position 8. This chemical is likely to be found in specialized applications due to its intricate structure, potentially in pharmaceuticals or as an intermediate in the synthesis of other complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 77940-52-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,4 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77940-52:
(7*7)+(6*7)+(5*9)+(4*4)+(3*0)+(2*5)+(1*2)=164
164 % 10 = 4
So 77940-52-4 is a valid CAS Registry Number.

, p. 2310 - 2317 (2007/10/21)

Strained pentacyclic ketones (5a-d) were prepared in high yields by photoinduced [4 + 2]π cycloadduct of N-(ethoxycarbonyl)azepine with substituted cyclopentadienones. The structure of one of the cage ketones (5d) was confirmed by X-ray analysis to be 1,2
