Check Digit Verification of cas no

The CAS Registry Mumber 349647-31-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,9,6,4 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 349647-31:
(8*3)+(7*4)+(6*9)+(5*6)+(4*4)+(3*7)+(2*3)+(1*1)=180
180 % 10 = 0
So 349647-31-0 is a valid CAS Registry Number.

Formation of disubstituted β-lactones using bifunctional catalysis

Calter, Michael A.,Tretyak, Olexandr A.,Flaschenriem, Christine

, p. 1809 - 1812 (2005)

(Chemical Equation Presented) Acid chlorides and aromatic aldehydes react in the presence of a stoichiometric amount of a tertiary amine and catalytic amounts of a cinchona alkaloid derivative and a Lewis acid to produce β-lactones in high diastereo- and

Diazo reactions with unsaturated compounds: V.1 reaction of phenyl vinyl ether with arenediazonium chlorides

Naidan

, p. 1600 - 1602 (2007/10/03)

Phenyl vinyl ether reacts with arenediazonium chlorides in aqueous acetone at pH 3-4 in the presence of a catalytic amount of copper(II) chloride to give arylacetaldehydes and small amounts 1-aryl-2-phenoxyethenes. No reaction occurs between the same reactants in the presence of sulfur(IV) oxide. 2000 MAIK "Nauka/Interperiodica".
