Calculate Digit Verification of CAS Registry Number 103681-53:
(8*1)+(7*0)+(6*3)+(5*6)+(4*8)+(3*1)+(2*5)+(1*3)=104
104 % 10 = 4
So 103681-53-4 is a valid CAS Registry Number.

Zur Reaktion von Cyclopropenonen mit Azomethinen; VII. Diphenylcyclopropenon und cyclische Amidine: Synthese von bi- und tricyclischen Pyrrolinon-Derivaten

Eicher, Theophil,Rohde, Ralph

, p. 619 - 625 (1985)

Reaction of diphenylcyclopropenone (1) with cyclic amidines 2 or 10-13 gives rise to bi- and tricyclic pyrrolinone derivatives of different structural types (3 or 14-17), which can be transformed in simple sequences to pyrrolinone-annellated heterobi- and -tricyclic compounds (7, 18-21).
