Calculate Digit Verification of CAS Registry Number 104143-72:
(8*1)+(7*0)+(6*4)+(5*1)+(4*4)+(3*3)+(2*7)+(1*2)=78
78 % 10 = 8
So 104143-72-8 is a valid CAS Registry Number.

ν-Triazolines, XXVI. 1,2,5-Trisubstituted 3-Pyrrolecarbaldehydes from N-Substituted Oxazolium-5-olates and 5-Amino-4,5-dihydro-4-methylene-ν-triazoles

, p. 1083 - 1089 (2007/10/02)

Die Cycloaddition von einigen symmetrisch und unsymmetrisch substituierten N-substituierten Oxazolium-5-olaten (2) an 5-Amino-4,5-dihydro-4-methylen-ν-triazole (1) wird beschrieben.Durch regiospezifische Cycloaddition entstehen instabile Cycloaddukte, die sofort Kohlendioxid und Stickstoff unter Umlagerung zu 1,2,5-trisubstituierten 3-Pyrrolcarbaldehyd-anilen (3) eliminieren.Die Anile werden leicht zu den entsprechenden 1,2,5-trisubstituierten 3-Pyrrolcarbaldehyden (4) hydrolysiert.
