654640-09-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 654640-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,4,6,4 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 654640-09:
(8*6)+(7*5)+(6*4)+(5*6)+(4*4)+(3*0)+(2*0)+(1*9)=162
162 % 10 = 2
So 654640-09-2 is a valid CAS Registry Number.

Highly regio- and stereoselective synthesis of polysubstituted cyclopropane compounds via the Pd(0)-catalyzed coupling-cyclization reaction of 2-(2′,3′-allenyl)malonates with organic halides

Ma, Shengming,Jiao, Ning,Yang, Qing,Zheng, Zilong

, p. 6463 - 6466 (2007/10/03)

A new method for highly regio- and stereoselective synthesis of polysubstituted cyclopropane compounds via the Pd(0)-catalyzed coupling-cyclization reaction of 2-(2′,3′-allenyl)malonates with organic halides is described. In these reactions, the starting

Palladium-Catalyzed Highly Regio- and Stereoselective Addition of Organoboronic Acids to Allenes in the Presence of AcOH

Ma, Shengming,Jiao, Ning,Ye, Longwu

, p. 6049 - 6056 (2007/10/03)

The Pd0-catalyzed regio- and stereoselective addition of organoboronic acids to allenes leads to stereodefined tri- or tetrasubstituted alkenes. Furthermore, this method shows high substitutent-loading capability and tolerance of various substitutents. A hydropalladation-Suzuki coupling mechanism, which may account for the regio- and stereoselectivity, is proposed.
