Check Digit Verification of cas no

The CAS Registry Mumber 75519-88-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,1 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75519-88:
(7*7)+(6*5)+(5*5)+(4*1)+(3*9)+(2*8)+(1*8)=159
159 % 10 = 9
So 75519-88-9 is a valid CAS Registry Number.

Trapping reactions of 1-methoxyfuran endo-peroxides with 4-nitrobenzaldehyde oxime. Regio- and stereoselective synthesis of the first oxime O- ethers

Iesce, M. Rosaria,Cermola, Flavio,Guitto, Antonio,Giordano, Federico

, p. 475 - 478 (2007/10/03)

The synthesis of the title compounds by dye-sensitized photooxygenation of 2-methoxyfurans in the presence of 4-nitrobenzaldehyde oxime is described. The crystal structure determination of a derivative is also reported.

Photosensitized Oxidation of Furans. Part 13. Trapping Reactions of the Carbonyl Oxides Obtained from Some 2-Methoxy-5-phenylfurans

Graziano, M. Liliana,Iesce, M. Rosaria,Cimminiello, Guido,Scarpati, Rachele

, p. 1699 - 1704 (2007/10/02)

The dye-sensitized photo-oxygenation in methanol of the 2-methoxy-5-phenylfurans (1a-c), unsubstituted at C-4 with electron-withdrawing groups, leads to the hemiperacetals (4a-c).The reaction provides the first incontrovertible evidence for carbonyl oxide

Photosensitized Oxidation of Furans. III. Comparison Between Photochemically and Thermally Generated Singlet Oxygen Oxidation of 3-Methoxycarbonyl-2-methyl-5-phenylfuran

Graziano, M. L.,Iesce, M. R.,Carli, B.,Scarpati, R.

, p. 1105 - 1107 (2007/10/02)

Thermal conversion of furan endo-peroxide I, obtained by photosensitized oxidation of furan II, yields very similar results to those of the oxidation of the furan II by thermally generated singlet oxygen, showing that also in the latter case the endo-peroxide I is the key intermediate.A mechanistic interpretation of the furan II-singlet oxygen reaction is reported.
