91-89-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91-89-4 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91-89:
(4*9)+(3*1)+(2*8)+(1*9)=64
64 % 10 = 4
So 91-89-4 is a valid CAS Registry Number.

One-step synthesis of alpha-pyrones from acyl chlorides by the Stille reaction.

Thibonnet, Jerome,Abarbri, Mohamed,Parrain, Jean-Luc,Duchene, Alain

, p. 3941 - 3944 (2007/10/03)

Palladium-catalyzed stereoselective annulation of a functional vinylstannane by acyl chlorides gives the corresponding alpha-pyran-2-ones in good yields. This annulation most probably proceeds through a Stille reaction/cyclization sequence.

Lewis Acid-Promoted Disproportionation Reaction of Aromatic Vinyl Ethers and Acetals and Its Application to the Synthesis of Paracotoin

Gong, Young Dae,Tanaka, Hiroko,Iwasawa, Nobuharu,Narasaka, Koichi

, p. 2181 - 2185 (2007/10/03)

Aromatic vinyl ethers and acetals underwent a novel addition-fragmentation reaction affording olefins and esters in the presence of a Lewis acid. This reaction was applied to intramolecular cyclization reaction, giving five or six membered ring compounds in good yields. Paracotoin, an intermediate in the biosynthesis of shikimic acid, was synthesized using this cyclization reaction as the key step.
