Check Digit Verification of cas no

The CAS Registry Mumber 31678-58-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,6,7 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 31678-58:
(7*3)+(6*1)+(5*6)+(4*7)+(3*8)+(2*5)+(1*8)=127
127 % 10 = 7
So 31678-58-7 is a valid CAS Registry Number.

Green alternative solvents for the copper-catalysed arylation of phenols and amides

Sambiagio, Carlo,Munday, Rachel H.,John Blacker,Marsden, Stephen P.,McGowan, Patrick C.

, p. 70025 - 70032 (2016/08/06)

Investigation of the use of green organic solvents for the Cu-catalysed arylation of phenols and amides is reported. Alkyl acetates proved to be efficient solvents in the catalytic processes, and therefore excellent alternatives to the typical non-green solvents used for Cu-catalysed arylation reactions. Solvents such as isosorbide dimethyl ether (DMI) and diethyl carbonate also appear to be viable possibilities for the arylation of phenols. Finally, a novel copper catalysed acyl transfer process is reported.
