Calculate Digit Verification of CAS Registry Number 104555-19:
(8*1)+(7*0)+(6*4)+(5*5)+(4*5)+(3*5)+(2*1)+(1*9)=103
103 % 10 = 3

Lohrisch, Hans-Joachim,Kopanski, Lothar,Herrmann, Rupert,Schmidt, Holger,Steglich, Wolfgang

, p. 177 - 194 (2007/10/02)

A convergent synthesis of grevillins 1 starts from diazoesters 6 which are converted into 3-aryl-2-oxopropyl ethyl oxalates 4 via bromoketones 7.Cyclization of 4 leads to pyrandiones 2 which are condensed with aromatic aldehydes to yield 4-aryl-2-benzylid
