307930-64-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 307930-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,7,9,3 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 307930-64:
(8*3)+(7*0)+(6*7)+(5*9)+(4*3)+(3*0)+(2*6)+(1*4)=139
139 % 10 = 9
So 307930-64-9 is a valid CAS Registry Number.

Enantiotopos-selective C-H oxygenation catalyzed by a supramolecular ruthenium complex

Frost, James R.,Huber, Stefan M.,Breitenlechner, Stefan,Bannwarth, Christoph,Bach, Thorsten

supporting information, p. 691 - 695 (2015/03/04)

Spirocyclic oxindoles undergo an enantioselective oxygenation reaction (nine examples; e.r. up to 97:3) upon catalysis by a chiral ruthenium porphyrin complex (1 mol%). The catalyst exhibits a lactam ring, which is responsible for substrate association through hydrogen bonds, and an active ruthenium center, which is in a defined spatial relationship to the oxygenation substrate. DFT calculations illustrate the perfect alignment of the active site with the reactive C-H bond and suggest-in line with the kinetic isotope effect-an oxygen rebound mechanism for the reaction.

Synthesis of A2B6-type [36]octaphyrins: Copper(II)-metalation-induced fragmentation reactions to porphyrins and N-fusion reactions of meso-(3-thienyl) substituents

Mori, Hirotaka,Aratani, Naoki,Osuka, Atsuhiro

experimental part, p. 1340 - 1346 (2012/09/08)

5,10,15-Tris(pentafluorophenyl)tetrapyrromethane was efficiently prepared through a route involving stepwise diaroylation of 5- pentafluorophenyldipyrromethane. A2B6-type [36]octaphyrins were prepared by the cross condensation of the

Hydrogen generation by hangman metalloporphyrins

Lee, Chang Hoon,Dogutan, Dilek K.,Nocera, Daniel G.

supporting information; scheme or table, p. 8775 - 8777 (2011/07/30)

A cobalt(II) hangman porphyrin with a xanthene backbone and a carboxylic acid hanging group catalyzes the electrochemical production of hydrogen from benzoic and tosic acid in acetonitrile solutions. We show that CoIIH is exclusively involved i
