Check Digit Verification of cas no
The CAS Registry Mumber 126689-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,6,8 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 126689-05:
(8*1)+(7*2)+(6*6)+(5*6)+(4*8)+(3*9)+(2*0)+(1*5)=152
152 % 10 = 2
So 126689-05-2 is a valid CAS Registry Number.

The borylation of cyclopropanes catalyzed by the combination of (η6-mes)IrBpin3 or [Ir(COD)OMe]2 and a phenanthroline derivative is reported. The borylation occurs selectively at the methylene C-H bonds of the cyclopropane ring over methine or methyl C-H bonds. High diasteroselectivities were observed from reactions catalyzed by the combination of iridium and 2,9-Me2phenanthroline. The cyclopropylboronate esters that are generated are versatile synthetic intermediates that can be converted to trifluoroborate salts, boronic acids, cyclopropylarenes, cyclopropylamines, and cyclopropanols.

The invention provides catalysts and methods for preparing boronate esters. The methods can include the borylation of a secondary or primary C—H bond, for example, by contacting a reactant having a methylene or methyl and a diboron bis-ester in the presence of an effective catalyst. The contacting can be in the presence of an iridium complex, to effect borylation of the secondary or primary C—H bond, thereby providing the boronate ester. The boronate esters can be readily isolated and/or converted into other useful compounds and intermediates.
