Calculate Digit Verification of CAS Registry Number 1342313-03:
(9*1)+(8*3)+(7*4)+(6*2)+(5*3)+(4*1)+(3*3)+(2*0)+(1*3)=104
104 % 10 = 4
So 1342313-03-4 is a valid CAS Registry Number.

Enantioselective organocatalytic formal allylation of α-branched aldehydes

Rodrigo, Eduardo,Morales, Sara,Duce, Sara,Ruano, Jose Luis Garcia,Cid, M. Belen

supporting information; experimental part, p. 11267 - 11269 (2011/12/05)

Heteroarylvinyl sulfone 1 has been successfully used as a new sulfonyl Michael acceptor in aminocatalytic reactions with branched aldehydes. Subsequent one-pot Julia-Kocienski olefination allows the challenging preparation of enantiomerically pure α-allylated aldehydes bearing C-α quaternary carbons.
