Check Digit Verification of cas no
The CAS Registry Mumber 1073355-02-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,7,3,3,5 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1073355-02:
(9*1)+(8*0)+(7*7)+(6*3)+(5*3)+(4*5)+(3*5)+(2*0)+(1*2)=128
128 % 10 = 8
So 1073355-02-8 is a valid CAS Registry Number.

We report a simple method for copper-catalyzed benzylic C-H alkynylation that uses alkynylboronic esters as nucleophilic coupling partners. The catalytic system is readily available and the reaction takes place under mild conditions. Different substrates for the C-H functionalization, as well as various alkynylboronic ester nucleophiles, were evaluated. Finally, three examples of enantioselective C-H alkynylations are presented.
