Calculate Digit Verification of CAS Registry Number 675855-49:
(8*6)+(7*7)+(6*5)+(5*8)+(4*5)+(3*5)+(2*4)+(1*9)=219
219 % 10 = 9
So 675855-49-9 is a valid CAS Registry Number.

Reductive lithiation of alkoxy-substituted benzyl methyl ethers and connection with cross-coupling reactions

Azzena, Ugo,Dettori, Giovanna,Pireddu, Roberta,Pisano, Luisa

, p. 1617 - 1623 (2007/10/03)

2-and 4-Ethoxymethoxybenzyl methyl ethers were employied as useful starting materials for the synthesis of 1,2- or 1,4-dicarbo-substituted benzenes. The proposed reaction sequence involves connection between the reductive lithiation of benzyl alkyl ethers and the metal-catalyzed cross-coupling reaction of aromatic triflates.
