Calculate Digit Verification of CAS Registry Number 1034558-64:
(9*1)+(8*0)+(7*3)+(6*4)+(5*5)+(4*5)+(3*8)+(2*6)+(1*4)=139
139 % 10 = 9
So 1034558-64-9 is a valid CAS Registry Number.

Diels-alder reactions of a styrene-isocyanate: Unexpected formation of a pyridinone and uracil

Gfesser, Gregory A.,Whittern, David,Cowart, Marlon D.,Faghih, Ramin

, p. 1199 - 1203 (2008)

During the preparation of 6-bromoisoquinolinone, a novel and unexpected reaction occurred to form a pyridinone and a pyrimidine-2,4-dione. We propose a [4+2] Diels-Alder dimerization of an intermediate styrene-isocyanate to explain the observed products.
