Calculate Digit Verification of CAS Registry Number 3448-36:
(6*3)+(5*4)+(4*4)+(3*8)+(2*3)+(1*6)=90
90 % 10 = 0
So 3448-36-0 is a valid CAS Registry Number.

Ruder, Suzanne M.

, p. 53 - 58 (2007/10/02)

The reaction of ketophosphonium ylides with dimethyl acetylenedicarboxylate in aprotic solvents gave mixtures of Z and E alkene products.Under protic conditions the initial Michael adduct was protonated and gave Z and E isomers of the alkene product as well.Depending on the alkyl group of the ketoylide, different product ratios were seen.Key words: Ketophosphonium ylide, dimethyl acetylenedicarboxylate, rearrangement, Michael addition.
