Check Digit Verification of cas no
The CAS Registry Mumber 29148-37-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,1,4 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 29148-37:
(7*2)+(6*9)+(5*1)+(4*4)+(3*8)+(2*3)+(1*7)=126
126 % 10 = 6
So 29148-37-6 is a valid CAS Registry Number.

The reaction of nitrile oxide-quinone cycloadducts. III. Reinvestigation of the base-induced isomerization of the 1:1 -C=C-adducts of aromatic nitrile oxides with 2,5-and 2,6-dialkyl-substituted p-benzoquinones

The structure of the product obtained by the base, induced isomerization of the 1,3-dipolar cycloadduct of 2,5-di-t-butyl-p-benzoquinone with 2,6- dichlorobenzonitrile oxide was determined by X-ray analysis. The t-butyl group at the bridgehead position of the 1,3-dipolar cycloadduct migrated to the neighboring carbonyl carbon atom. This base-induced rearrangement took place with a bulky group, i.e., Et, i-Pr, t-Bu, and Bn at the bridgehead position of nitrile oxide-quinone cycloadducts in an alcoholic media. The driving force of this reaction is considered to be due to stabilization by aromatization from isoxazoline derivatives to isoxazole-fused p-quinol derivatives.
