Check Digit Verification of cas no

The CAS Registry Mumber 7307-04-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,0 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7307-04:
(6*7)+(5*3)+(4*0)+(3*7)+(2*0)+(1*4)=82
82 % 10 = 2
So 7307-04-2 is a valid CAS Registry Number.

Steric vis-à-vis electronic influence of phosphines on biaryl motif: Ligand design for coupling reactions with Chloroarenes

Saha, Debajyoti,Ghosh, Raju,Dutta, Ranjan,Mandal, Achintya Kumar,Sarkar, Amitabha

, p. 89 - 97 (2015/01/09)

In order to assess relative contribution of steric factors and electron-richness of phosphine ligands on biaryl-type scaffolds, a set of 1-aryl-pyrazole/pyrrole derived ligands L1-L6 featuring either aryldicyclohexylphosphino or aryldiphenylphosphino donor group was synthesized. A bidentate coordination mode of ligands L1 or L2 was evident from a representative crystal structure that implied a possible hemilabile participation to facilitate catalytic steps. With N-arylpyrroles (L3-L5), where the second nitrogen donor on the heterocycle is absent, coupling reactions of unactivated chloroarenes still proceeded with comparable efficiency. Thus, suitably endowed triarylphosphines were found to be as efficient as more expensive aryldialkylphosphine analogs in reactions with chloroarenes, extending the scope of ligand design.

METHOD FOR EXTRACTING ASYMMETRIC B-DIKETONE COMPOUND FROM B-DIKETONE COMPOUND

-

Paragraph 0074-0076, (2015/11/16)

The present invention provides a method of extracting an asymmetric β-diketone compound from a β-diketone compound containing at least one symmetric β-diketone compound mixed in the asymmetric β-diketone compound, and the method includes the step (A) of adjusting a pH of a mixed solution of the β-diketone compound and water at 11.5 or more and dissolving the β-diketone compound into water to form a β-diketone compound solution and the step (B) of subsequently adjusting the pH of the β-diketone compound solution at 9.5 or less and recovering the asymmetric β-diketone compound of Chemical Formula 1 separated from the β-diketone compound solution. The present invention further includes at least either (a) a step of setting the upper limit of the pH of the mixed solution to 12.5 to form a β-diketone compound solution in the step (A) and bringing the β-diketone compound solution into contact with a hydrophobic solvent or (b) a step of setting the lower limit of the pH of the β-diketone compound solution to 8.0 in the step (B).

PROCESSES FOR PREPARING β-DIKETONE COMPOUND, METAL COMPLEX THEREOF AND METALLIC COMPOUND

-

Page/Page column 26, (2008/06/13)

Disclosed is a process for preparing a β-diketone compound such as 2,6-dimethyl-3,5-heptanedione, which comprises reacting an ester compound such as an alkyl isobutyrate with a ketone compound such as 3-methylbutanone in the presence of an alkali metal alkoxide as a catalyst. The process comprises a step 1 in which an ester compound CR1R2R3COOQ is reacted with a ketone compound CR4R5R6COCH2R7 using an alkali metal alkoxide catalyst to give a β-diketone compound CR1R2R3COCHR4R5R6. (In the formulae, R7 is hydrogen or an alkyl group of 1 to 4 carbon atoms while others are each independently hydrogen or an alkyl group of 1 to 3 carbon atoms, and at least one of R1 to R6 is hydrogen.)
