31582-29-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31582-29-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,8 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 31582-29:
(7*3)+(6*1)+(5*5)+(4*8)+(3*2)+(2*2)+(1*9)=103
103 % 10 = 3
So 31582-29-3 is a valid CAS Registry Number.

Pyridine Nucleus Hydroxylation with Copper Oxygenase Models

Reglier, Marius,Amadei, Edith,Tadayoni, Rahim,Waegell, Bernard

, p. 447 - 450 (1989)

Reaction of iodosylbenzene with CuI complexes (2a,b) occurs with hydroxylation in the ortho position of one pyridine nucleus; CuIII=O species are postulated.

Benzylic ligand hydroxylation starting from a dicopper μ- I·2:I·2 peroxo intermediate: Dramatic acceleration of the reaction by hydrogen-atom donors

Rolff, Malte,Hamann, Jessica Nadine,Tuczek, Felix

supporting information; experimental part, p. 6924 - 6927 (2011/08/06)

Radicals in directed pathways: The μ-I·2: I·2 peroxo CuII2 intermediate 1 shows a much faster benzylic ligand hydroxylation than systems without phenol. This novel reactivity can be further accelerated by addition of external H-atom donors such as TEMPO-H. The results imply initial H-atom transfer leading to the formation of phenoxyl radicals. A highly reactive copper oxyl intermediate is then formed, which inserts oxygen into the benzylic C-H bond. Copyright
