Check Digit Verification of cas no

The CAS Registry Mumber 1590442-52-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,9,0,4,4 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1590442-52:
(9*1)+(8*5)+(7*9)+(6*0)+(5*4)+(4*4)+(3*2)+(2*5)+(1*2)=166
166 % 10 = 6
So 1590442-52-6 is a valid CAS Registry Number.

PdII-catalyzed mild C-H ortho arylation and intramolecular amination oriented by a phosphinamide group

Guan, Jing,Wu, Guo-Jie,Han, Fu-She

, p. 3301 - 3305 (2014/04/03)

A novel protocol for the Pd-catalyzed ortho-arylation of aryl phosphinamide with boronic acid is reported. By using phosphinamide as a new directing group, the reaction proceeds efficiently under mild conditions at 40 °C. Mechanistic studies reveal that the reaction proceeds via a PdII to Pd0 cycle. The phosphinamide group is also shown to be an effective orienting group for direct C-H amination.
