Calculate Digit Verification of CAS Registry Number 144945-89:
(8*1)+(7*4)+(6*4)+(5*9)+(4*4)+(3*5)+(2*8)+(1*9)=161
161 % 10 = 1
So 144945-89-1 is a valid CAS Registry Number.

Synthesis of 6H-Dibenzopyran-6-ones via Dienone-Phenol Rearrangements of Spiro-3'-ones

Hart, David J.,Kim, Adrienne,Krishnamurthy, Ramanarayanan,Merriman, Gregory H.,Waltos, Anne-Marie

, p. 8179 - 8188 (2007/10/02)

A series of spiro-3'-ones were prepared from metallated benzamides and 4,4-dimethoxycyclohexadienone.Rearrangement of these spirodienones under a variety of conditions gave substituted 6H-dibenzopyran-6-ones.Rearrangements in aqueous sulfuric acid gave products of formal O-migration while rearrangements in trifluoroacetic anhydride-trifluoroacetic acid-sulfuric acid usually gave C-migration products.Key Words: dienone-phenol rearrangement; 6H-dibenzopyran-6-one, spiro-3'-one
