765319-28-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 765319-28-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,5,3,1 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 765319-28:
(8*7)+(7*6)+(6*5)+(5*3)+(4*1)+(3*9)+(2*2)+(1*8)=186
186 % 10 = 6
So 765319-28-6 is a valid CAS Registry Number.

A palladium-catalyzed enantioselective alkylative desymmetrization of meso-succinic anhydrides

Bercot, Eric A.,Rovis, Tomislav

, p. 10248 - 10249 (2004)

Monoalkylation of cyclic anhydrides provides an opportunity to couple a carbon-carbon bond-forming event with the control of backbone stereochemistry. We have developed a palladium-JOSIPHOS catalyst system that desymmetrizes meso-succinic anhydrides using organozinc reagents as nucleophiles, and have found that, in many cases, this reaction proceeds at ambient temperature.

Selective substituent transfer from mixed zinc reagents in Ni-catalyzed anhydride alkylation

Johnson, Jeffrey B.,Yu, Robert T.,Fink, Paul,Bercot, Eric A.,Rovis, Tomislav

, p. 4307 - 4310 (2007/10/03)

(Chemical Equation Presented) The use of mixed zinc reagents in Ni-catalyzed anhydride alkylation results in preferential transfer of substituents (Ph > Me > Et ? iPr ~ TMSCH2) for the ligands bipy, dppe, and iPrPHOX. Utilization of such mixed
