Check Digit Verification of cas no
The CAS Registry Mumber 1073339-12-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,7,3,3,3 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1073339-12:
(9*1)+(8*0)+(7*7)+(6*3)+(5*3)+(4*3)+(3*9)+(2*1)+(1*2)=134
134 % 10 = 4
So 1073339-12-4 is a valid CAS Registry Number.

A catalytic borylation/dehalogenation route to o -fluoro arylboronates

A two-step Ir-catalyzed borylation/Pd-catalyzed dehalogenation sequence allows for the net synthesis of fluoroarenes where the boronic ester is ortho to fluorine. Key elements of this approach include the use of a halogen para to the fluorine to block meta Ir-catalyzed borylation and the chemoselective Pd-catalyzed dehalogenation by KF activated polymethylhydrosiloxane (PMHS).
