Check Digit Verification of cas no

The CAS Registry Mumber 117733-36-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,7,3 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 117733-36:
(8*1)+(7*1)+(6*7)+(5*7)+(4*3)+(3*3)+(2*3)+(1*6)=125
125 % 10 = 5
So 117733-36-5 is a valid CAS Registry Number.

1,3-Dipolar Cycloaddition Reactions of 1-Aryl-N-methyl-2-(1H-azol-1-yl)-ethanimine N-Oxides to Olefins

Mullen, George B.,Bennett, Grace A.,Swift, Patricia A.,Marinyak, David M.,Dormer, Peter G.,Georgiev, Vassil St.

, p. 105 - 107 (2007/10/02)

The regio- and stereoselectivity of the 1,3-dipolar cycloaddition reaction of 1-aryl-N-methyl-2-(1H-azol-1-yl)ethanimine N-oxides 6 to monosubstituted olefins 7 were investigated.The reaction is regioselective, leading to the corresponding C-5 substituted isoxazolidines 8/9 as cis/trans diastereomeric mixtures.The cis isomers, which are the predominant species of the mixtures, are readily separated by flash chromatography on neutral silica gel.
