Check Digit Verification of cas no

The CAS Registry Mumber 1501945-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,0,1,9,4 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1501945-40:
(9*1)+(8*5)+(7*0)+(6*1)+(5*9)+(4*4)+(3*5)+(2*4)+(1*0)=139
139 % 10 = 9
So 1501945-40-9 is a valid CAS Registry Number.

Development of an air-stable nickel precatalyst for the amination of aryl chlorides, sulfamates, mesylates, and triflates

Park, Nathaniel H.,Teverovskiy, Georgiy,Buchwald, Stephen L.

supporting information, p. 220 - 223 (2014/01/23)

A new air-stable nickel precatalyst for C-N cross-coupling is reported. The developed catalyst system displays a greatly improved substrate scope for C-N bond formation to include both a wide range of aryl and heteroaryl electrophiles and aryl, heteroaryl, and alkylamines. The catalyst system is also compatible with a weak base, allowing the amination of substrates containing base-sensitive functional groups.
