Calculate Digit Verification of CAS Registry Number 92744-70:
(7*9)+(6*2)+(5*7)+(4*4)+(3*4)+(2*7)+(1*0)=152
152 % 10 = 2
So 92744-70-2 is a valid CAS Registry Number.

DIRECTION OF HETEROCYCLIZATION IN THE INTERACTION OF SEMICYCLIC 1,5-DIKETONES WITH BIFUNCTIONAL NUCLEOPHILES

Donchak, L. N.,Saverchenko, A. N.,Kaminskii, V. A.,Tilichenko, M. N.

, p. 779 - 783 (2007/10/02)

In the interaction of a series of 1-aryl-3-R-3-(2'-oxo-cycloalkyl)-1-propanones with o-aminophenol and o-phenylenediamine, depending on the structure of the reacting compounds, derivatives of 1,9a-tetra(tri)-methylene-9-oxa(aza)-4a-aza-1,2,4a,9a-tetrahydrofluorene are formed.The interaction of 1-(o-hydroxyphenyl)- and 1-(o-aminophenyl)-3-R-3-(2'-oxocycloalkyl)-1-propanones with o-aminophenol, o-phenylenediamine, ethanolamine, and ethylenediamine leads to the formation of new heterocyclic systems: 2,7-dioxa-5-azatricyclo1,5>dodecane, 7-oxa-2,5-diazatricyclo1,5>dodecane, and 2,5,7-triazatricyclo1,5>dodecane.
