Check Digit Verification of cas no

The CAS Registry Mumber 26507-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,5,0 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 26507-91:
(7*2)+(6*6)+(5*5)+(4*0)+(3*7)+(2*9)+(1*1)=115
115 % 10 = 5
So 26507-91-5 is a valid CAS Registry Number.

Benzylic hydroxylation of aromatic compounds by P450 BM3

Neufeld, Katharina,Marienhagen, Jan,Schwaneberg, Ulrich,Pietruszka, Joerg

, p. 2408 - 2421 (2013/09/12)

Cytochrome P450 BM3 monooxygenase from Bacillus megaterium and its variants are promising catalysts for organic synthesis. Aiming at the identification of variants for selective hydroxylation of functionalised aromatic compounds, the double mutant F87A L188C showed remarkably improved catalytic activity towards a set of tested toluene derivatives. The apparent catalytic efficiency of this variant towards the model substrate methyl 2-methoxy-3-methylbenzoate was 63.6 s-1 M-1, which is 535-fold higher compared to that of wild-type BM3. Furthermore, the double mutant selectively catalysed the benzylic hydroxylation of numerous toluene derivatives, especially in the presence of carbonyl- or carboxyl-functions that are directly attached to the aromatic ring. Preparative scale conversion resulted in efficient production of methyl 3-(hydroxymethyl)-2-methoxybenzoate (73% yield) which proved that F87A L188C is a suitable, efficient and sustainable catalyst for the introduction of benzylic hydroxyl groups in general.

Synthesis and application of oxadiazines as chiral ligands for the enantioselective addition of diethylzinc to aldehydes

Dean, Melissa A.,Hitchcock, Shawn R.

experimental part, p. 2471 - 2478 (2011/02/22)

A series of oxadiazines derived from l-phenylalanine bearing phenolic substituents have been synthesized in a multistep, one pot process. This process involves the reaction of a mixed anhydride with a β-hydrazino alcohol, methanesulfonylation of the alcohol moiety, and base induced cyclization. The resultant oxadiazines were employed in the asymmetric addition of diethylzinc to aldehydes.

LUMINESCENT MACROCYCLIC LANTHANIDE COMPLEXES

-

Page/Page column 74, (2008/12/05)

The present invention provides a novel class of macrocyclic compounds as well as complexes formed between a metal (e.g., lanthanide) ion and the compounds of the invention. Preferred complexes exhibit high stability as well as high quantum yields of lanthanide ion luminescence in aqueous media without the need for secondary activating agents. Preferred compounds incorporate hydroxy-isophthalamide moieties within their macrocyclic structure and are characterized by surprisingly low, non-specific binding to a variety of polypeptides such as antibodies and proteins as well as high kinetic stability. These characteristics distinguish them from known, open-structured ligands.
