Check Digit Verification of cas no

The CAS Registry Mumber 102028-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,0,2 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 102028-01:
(8*1)+(7*0)+(6*2)+(5*0)+(4*2)+(3*8)+(2*0)+(1*1)=53
53 % 10 = 3
So 102028-01-3 is a valid CAS Registry Number.

Copper(ii)-catalyzed Chan-Lam cross-coupling: chemoselective N-arylation of aminophenols

Copper(ii)-catalyzed boronic acid promoted chemoselective N-arylation of unprotected aminophenols has been developed. Selective N-arylation of 3-aminophenol is achieved with a Cu(OAc)2/AgOAc combination in MeOH at rt, whereas the chemoselective N-arylated products of 4-aminophenol can be obtained with a Cu(OAc)2/Cs2CO3 system and benzoic acid as an additive. These ligand-free conditions and “open-flask” chemistry are robust and compatible with a wide range of functional groups. The mechanistic investigation for this selective N-arylation has been studied by considering Density Functional Theory (DFT) calculations.
