Check Digit Verification of cas no

The CAS Registry Mumber 1224720-35-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,4,7,2 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1224720-35:
(9*1)+(8*2)+(7*2)+(6*4)+(5*7)+(4*2)+(3*0)+(2*3)+(1*5)=117
117 % 10 = 7
So 1224720-35-7 is a valid CAS Registry Number.

A combined spin trapping/EPR/mass spectrometry approach to study the formation of a cyclic peroxide by dienolic precursor autoxidation

Triquigneaux, Mathilde,Charles, Laurence,Andre-Barres, Christiane,Tuccio, Beatrice

body text, p. 1361 - 1367 (2010/06/17)

The spontaneous addition of air oxygen to a dienolic compound, yielding a cyclic peroxide, was followed by spin trapping (ST) combined with EPR spectroscopy and mass spectrometry (MS). Using two different nitrones, the ST/EPR study allowed the detection of the spin adduct of a radical intermediate, and the radical centre in the addend was identified after similar experiments performed with two different 13C-labelled analogues of the substrate. The media were also submitted to electrospray ionisation, in both positive and negative modes, for structural characterisation of the spin adducts by tandem mass spectrometry. This allowed the structure of the hydroxylamine derivatives of the nitroxides formed to be identified. Following these results, a mechanism pathway was proposed for this autoxidation.
