105065-05-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 105065-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,0,6 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 105065-05:
(8*1)+(7*0)+(6*5)+(5*0)+(4*6)+(3*5)+(2*0)+(1*5)=82
82 % 10 = 2
So 105065-05-2 is a valid CAS Registry Number.

Addition Reactions of (Phenylsulfonyl)propadiene with 1-Pyrrolidinyl Enamines of Cyclic Ketones: Syntheses and Reactions of 1,3-Dienes Possessing an Allyl Sulfone Moiety

Hayakawa, Kenji,Takewaki, Makoto,Fujimoto, Ichiro,Kanematsu, Ken

, p. 5100 - 5105 (2007/10/02)

Addition reactions of (phenylsulfonyl)propadiene (1) with various 1-pyrrolidinyl enamines have been investigated.Allene 1 and enamines of cyclic ketones (2, 7-14) readily underwent the Michael-type addition reactions at -50 deg C to give the adducts 3, 15-20, and/or their isomers 4 and 21-26, which apparently arose by base-catalyzed isomerization of the former.These adducts were conveniently converted into the corresponding 1,3-dienes possessing allyl sulfone moiety (28, 38-45) through allyl acetates (27, 30-37) by base-promoted (n-BuLi, -50 deg C) 1,4-elimination of acetic acid to vinyl sulfones followed by deconjugation to allyl sulfones.The synthetic versatility of these dienes was revealed by the Diels-Alder reactions with dimethyl acetylenedicarboxylate (DMAD) and alkylation reactions via α-sulfonyl carbanions.
