Check Digit Verification of cas no
The CAS Registry Mumber 5547-35-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,4 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5547-35:
(6*5)+(5*5)+(4*4)+(3*7)+(2*3)+(1*5)=103
103 % 10 = 3
So 5547-35-3 is a valid CAS Registry Number.

ortho-C?H Arylation of Benzoic Acids with Aryl Bromides and Chlorides Catalyzed by Ruthenium

A system consisting of catalytic amounts of [(p-cym)RuCl2]2/PEt3?HBF4, K2CO3as the base, and NMP as the solvent efficiently mediates the ortho-C?H arylation of benzoic acids with aryl bromides at 100 °C. Replacing the phosphine ligand with the amino acid dl-pipecolinic acid enables the analogous transformation with aryl chlorides. The key advantage of this broadly applicable transformation is the use of an inexpensive ruthenium catalyst in combination with simple carboxylates as directing groups, which can either be tracelessly removed or used as anchor points for decarboxylative ipso substitutions.
Two methods for direct ortho-arylation of benzoic acids

Two new palladium-catalyzed methods for the direct ortho-arylation of free benzoic acids have been developed. The first method employs stoichiometric silver acetate for iodide removal, aryl iodide as the coupling partner, and acetic acid solvent. This method is applicable to the arylation of electron-rich to moderately electron-poor benzoic acids and tolerates chloride and bromide substituents on both coupling partners. The second method involves the use of aryl chloride, cesium carbonate base, n-butyl-di-1-adamantylphosphine ligand, and DMF solvent and is suitable for both electron-rich and electron-poor benzoic acids. Mechanistic studies of the second method point to the heterolytic C-H bond cleavage as the rate-determining step.
