Check Digit Verification of cas no

The CAS Registry Mumber 3301-94-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,0 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3301-94:
(6*3)+(5*3)+(4*0)+(3*1)+(2*9)+(1*4)=58
58 % 10 = 8
So 3301-94-8 is a valid CAS Registry Number.

Synthesis method of deltalactone

-

Paragraph 0019-0020; 0025-0026; 0031-0032, (2017/08/29)

The invention discloses a synthesis method of deltalactone. The synthesis method is characterized by comprising the following steps: taking 5-oxo fatty acid as a starting raw material, and reacting under hydrogen pressure of 5atm to 30atm and at 120 DEG C to 180 DEG C in the presence of catalysts including Ru/C and the like; firstly, carrying out a hydrogenation reaction of carbonyl to obtain an intermediate product 5-hydroxyl fatty acid M1; meanwhile, carrying out intramolecular dehydration and esterification on M1 and carrying out a one-pot reaction to generate the deltalactone. A specific reaction formula is shown in the description, wherein R=CH3(CH2)n- and n is equal to 1 to 8.

New strategies in carbonylation chemistry: The synthesis of δ-lactones from saturated alcohols and CO

Tsunoi, Shinji,Ryu, Ilhyong,Okuda, Tohru,Tanaka, Minoru,Komatsu, Mitsuo,Sonoda, Noboru

, p. 8692 - 8701 (2007/10/03)

This paper describes the δ-carbonylation of saturated alcohols which uses a 1,5-hydrogen-transfer reaction of alkoxyl radicals and subsequent carbonylation at the δ-carbon atoms as the key. The carbonylation reactions of five classes of saturated alcohols, namely, primary alcohols having primary δ-carbons, primary alcohols having secondary δ-carbons, primary alcohols having tertiary δ-carbons, secondary alcohols having primary δ- carbons, secondary alcohols having secondary δ-carbons, were carded out, in which lead tetraacetate (LTA) was used as a one-electron oxidant to generate the alkoxyl radicals. Carbonylation of these saturated alcohols, except for primary alcohols having tertiary δ-carbons, took place to afford δ-lactones in moderate to good yields. The mechanism of the remote carbonylation likely involves (1) alkoxyl radical generation via LTA oxidation of a saturated alcohol, (2) conversion of this alkoxyl radical to a δ-hydroxyalkyl radical by a 1,5-hydrogen-transfer reaction, (3) CO trapping of the δ-hydroxyalkyl radical yielding an acyl radical, and (4) oxidation and cyclization of the acyl radical to give a δ-lactone. A metal salt-free system was also tested for a substrate derived from a tertiary alcohol having a secondary δ- carbon; the photolysis of an alkyl 4-nitrobenzenesulfenate under CO pressures gave a δ-lactone in moderate yield.

PHASE TRANSFER CATALYSIS AND HOMOGENEOUS REACTIONS WITH β-OXYALKYL RADICALS FROM ORGANOMERCURIALS

Barluenga, Jose,Lopez-Prado, Joaquin,Campos, Pedro J.,Asensio, Gregorio

, p. 2863 - 2868 (2007/10/02)

β-Alkoxy- and β-hydroxyalkyl radicals generated by sodium borohydride reduction of oxymercurials react with electron deficient olefins to give addition compounds in a homogeneous process.Heterogeneous reactions are also successful in the presence of catalytic amounts of surfactants and provide a superior method for the "one pot" reductive alkylation of oxymercurials.
