3206-45-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3206-45-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,0 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3206-45:
(6*3)+(5*2)+(4*0)+(3*6)+(2*4)+(1*5)=59
59 % 10 = 9
So 3206-45-9 is a valid CAS Registry Number.

METHOD FOR PRODUCING ALKENE STEREOSELECTIVELY

-

Paragraph 0050; 0051, (2017/08/03)

PROBLEM TO BE SOLVED: To provide a method for producing alkene efficiently and stereoselectively, and tetrazole that is a reaction intermediate useful for the production method and represented by formula (2). SOLUTION: The present invention provides a met

Phosphabarrelenes as ligands in rhodium-catalyzed hydroformylation of internal alkenes essentially free of alkene isomerization

Fuchs, Evelyn,Keller, Manfred,Breit, Bernhard

, p. 6930 - 6939 (2007/10/03)

Despite significant research efforts in the past, one of the remaining problems to be solved in industrially important hydroformylation is the chemoselective low-pressure hydroformylation of internal alkenes. We report here on a new class of phosphabarrelene/rhodium catalysts 2 that display very high activity towards hydroformylation of internal alkenes with an unusually low tendency towards alkene isomerization. Preparation of new phosphabarrelene ligands, studies of their coordination properties, as well as results obtained in the rhodium-catalyzed hydroformylation of cyclic and acyclic internal alkenes are reported.
