611-31-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 611-31-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 611-31:
(5*6)+(4*1)+(3*1)+(2*3)+(1*1)=44
44 % 10 = 4
So 611-31-4 is a valid CAS Registry Number.

Nitrile Oxide Cycloaddtion Routes to 2-(Isoxazolyl)benzoates and 2-(1,2,4-Oxadiazol-3-yl)benzoates

Howe, Robert K.,Schleppnik, Frances M.

, p. 721 - 726 (2007/10/02)

Cycloaddition of aromatic nitrile oxides to methyl o-vinylbenzoate produced methyl 2-(3-aryl-2-isoxazolin-5-yl)benzoates; the isoxazolines were converted to methyl 2-(3-arylisoxazol-5-yl)benzoates.Reaction of the nitrile oxide from o-methoxycarbonylbenzohydroximinoyl chloride (11) with phenylacetylene, styrenes, and aromatic nitriles resulted in methyl 2-(5-phenylisoxazol-3-yl)benzoate, methyl 2-(5-aryl-2-isoxazolin-3-yl)benzoates (15) and methyl 2-(5-aryl-1,2,4-oxadiazol-3-yl)benzoates, respectively.The isoxazolines 15 were converted to the corresponding isoxazoles 16.
