5722-58-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5722-58-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,2 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5722-58:
(6*5)+(5*7)+(4*2)+(3*2)+(2*5)+(1*8)=97
97 % 10 = 7
So 5722-58-7 is a valid CAS Registry Number.

PHOTOLYSIS OF 2-ARYLOXY- OR 2-ARYLTHIO-1,3-BENZODIOXAN-4-ONES

Diaz-Mondejar, M. Rosa,Miranda, Miguel A.

, p. 1125 - 1131 (2007/10/02)

Photolysis of 1,3-benzodioxan-4-ones 3b and 4a gives mainly products derived from photorearrangement, photoreduction and/or photosolvolysis.These results closely parallel those obtained by irradiation of the isomeric open-chain compounds 1b and 2a.A mechanism involving the intermediacy of radical pairs A and B, generated by successive homolysis of the aryloxy- or arylthio-carbon and carbonyl-oxygen bonds, is proposed.
