Check Digit Verification of cas no

The CAS Registry Mumber 447413-03-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,7,4,1 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 447413-03:
(8*4)+(7*4)+(6*7)+(5*4)+(4*1)+(3*3)+(2*0)+(1*3)=138
138 % 10 = 8
So 447413-03-8 is a valid CAS Registry Number.

Copper-mediated hydroxylation of arenes and heteroarenes directed by a removable bidentate auxiliary

supporting information, p. 3904 - 3907 (2014/08/18)

A copper-mediated C-H hydroxylation of arenes and heteroarenes using our newly developed PIP directing group has been developed. This procedure is scalable and compatible with a wide range of functional groups and heteroarenes, providing an operationally simple protocol for the synthesis of o-hydroxybenzamides. The hydroxylation of nicotinamides gave 4-oxo-1,4-dihydropyridine-3-carboxamides selectively. Preliminary mechanistic studies implicate that a basic ligand-enabled, irreversible, rate-determining CMD step is most likely involved in this process.
