Check Digit Verification of cas no

The CAS Registry Mumber 57309-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,3,0 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 57309-13:
(7*5)+(6*7)+(5*3)+(4*0)+(3*9)+(2*1)+(1*3)=124
124 % 10 = 4
So 57309-13-4 is a valid CAS Registry Number.

Radical intermediates in the photorearrangement of 3-hydroxyindolic nitrones

Alberti, Angelo,Astolfi, Paola,Carloni, Patricia,Doepp, Dietrich,Greci, Lucedio,Rizzoli, Corrado,Stipa, Pierluigi

experimental part, p. 6889 - 6894 (2011/10/05)

A number of 3-hydroxy substituted indolic nitrones were found to quantitatively photorearrange to (2-benzoylamino)phenyl ketones upon UV-A irradiation. EPR-Spin Trapping experiments suggest that the process, which is believed to proceed via the formation

Stereospecific Reduction of 3-Hydroxy-3H-indoles and of their Corresponding N-Oxides with NaBH4 and LiAlH4. Synthesis of True 1-Hydroxy-2,3-disubstituted Indoles. Crystal and Molecular Structure of 3-Hydroxy-2,3-diphenylindoline

Berti, Corrado,Greci, Lucedio,Poloni, Marino,Andreetti, Giovanni Dario,Bocelli, Gabriele,Sgarabotto, Paolo

, p. 339 - 346 (2007/10/02)

3-Hydroxy-3H-indoles (1) and their corresponding N-oxides (5) undergo stereospecific reduction at the double C=N bond giving the indoline derivatives (2) and (6) respectively, which, in acidic medium, lose water to give the 2,3-disubstituted indoles (3) and (7) whose physical and spectroscopic data are not in agreement with those reported previously.The structure of 3-hydroxy-2,3-diphenylindoline, one of the reduction products, was determined by X-ray diffraction, and it was shown that hydrogen adds at C-2 cis to the hydroxy-group on C-3. 3,3-Disubstituted-3H-indoles with two organic radicals on C-3 give a mixture of stereoisomers.
