Check Digit Verification of cas no

The CAS Registry Mumber 55966-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,9,6 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55966-68:
(7*5)+(6*5)+(5*9)+(4*6)+(3*6)+(2*6)+(1*8)=172
172 % 10 = 2
So 55966-68-2 is a valid CAS Registry Number.

Highly Efficient Mechanochemical N-Arylation of Amino Alcohols and Diamines with Cu0 Powder

Martina, Katia,Rinaldi, Laura,Baricco, Francesca,Boffa, Luisa,Cravotto, Giancarlo

, p. 2789 - 2794 (2015/12/18)

Cu0-catalysed arylations have rightly acquired great importance over the last decade. This paper reports the N-arylation of amino alcohols and diamines with iodobenzene derivatives in a planetary ball mill and an investigation into the procedure. This newly developed solvent-free protocol is fast, efficient and occurs under the mechanochemical activation of metallic copper powder. It does not require additional ligands and gives excellent yields. This paper aims to broaden the scope of mechanochemical Cu0-activation and so a new one-pot, two-step synthesis that combines CuAAC and N-arylation has been successfully performed and reported herein.
