Calculate Digit Verification of CAS Registry Number 1020166-25:
(9*1)+(8*0)+(7*2)+(6*0)+(5*1)+(4*6)+(3*6)+(2*2)+(1*5)=79
79 % 10 = 9

Pyrimidines as Surrogates for 1,3-Dicarbonyl Compounds in peri Annulation of Perimidines en Route to 1,3-Diazapyrenes

Aksenov, Alexander V.,Shcherbakov, Stanisvlav V.,Lobach, Irina V.,Aksenova, Inna V.,Rubin, Michael

, p. 1666 - 1673 (2017)

A highly efficient protocol for acid-mediated peri annulation of perimidines with pyrimidines has been developed. Pyrimidines, used as surrogates for 1,3-dicarbonyl compounds, furnish benzo[gh]perimidines, which includes hardly available analogues, non-substituted, or mono-substituted at C-6, C-8. Limitations of reactions that use 5-bromopyrimidines are investigated.
