857682-06-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 857682-06-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,6,8 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 857682-06:
(8*8)+(7*5)+(6*7)+(5*6)+(4*8)+(3*2)+(2*0)+(1*6)=215
215 % 10 = 5
So 857682-06-5 is a valid CAS Registry Number.

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 (2006)

(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

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

Bercot, Eric A.,Rovis, Tomislav

, p. 10248 - 10249 (2007/10/03)

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.
