Calculate Digit Verification of CAS Registry Number 1449584-15:
(9*1)+(8*4)+(7*4)+(6*9)+(5*5)+(4*8)+(3*4)+(2*1)+(1*5)=199

supporting information, p. 870 - 879 (2013/08/15)

2H-Pyrans are constructed on a 1-oxa- or 1-azacyclohexane-2,4-dione core via Knoevenagel condensation with enals followed by 6π.electrocyclization, which are readily catalyzed with ethylenediammonium diacetate. This formal [3 + 3] strategy constitutes CO
