Check Digit Verification of cas no
The CAS Registry Mumber 628333-86-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,8,3,3 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 628333-86:
(8*6)+(7*2)+(6*8)+(5*3)+(4*3)+(3*3)+(2*8)+(1*6)=168
168 % 10 = 8
So 628333-86-8 is a valid CAS Registry Number.

Alternative biarylphosphines for use in the palladium-catalyzed amination of aryl halides

Two families of biarylphosphine ligands were prepared for use in the Pd-catalyzed amination reaction. The first series investigated was derived from N-phenylpyrroles, and the second, was derived from N-phenylpyrazoles. While the pyrrole ligands were not as general in substrate scope, one of the readily prepared pyrazole ligands (R = t-Bu) was found to have a fairly broad substrate scope.
