133157-43-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133157-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,1,5 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133157-43:
(8*1)+(7*3)+(6*3)+(5*1)+(4*5)+(3*7)+(2*4)+(1*3)=104
104 % 10 = 4
So 133157-43-4 is a valid CAS Registry Number.

A New Method for Obtaining 1H NMR Structural Information on Nitroxide Spin Labels Through Reduction to Hydroxylamine by Radiolysis of their Methanolic Solutions

Brik, M. E.,Remita, H.,Delcourt, M. O.

, p. 24 - 25 (1991)

A preliminary description of a convenient method for the reduction of nitroxide spin labels by a radiolysis technique is described; the main advantage of this procedure is the ease with which nitroxides are converted to the corresponding non-paramagnetic hydroxylamines, the 1H NMR spectra of these hydroxylamines gives structural information on the parent spin labels.
