Check Digit Verification of cas no

The CAS Registry Mumber 1232407-18-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,2,4,0 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1232407-18:
(9*1)+(8*2)+(7*3)+(6*2)+(5*4)+(4*0)+(3*7)+(2*1)+(1*8)=109
109 % 10 = 9
So 1232407-18-9 is a valid CAS Registry Number.

Palladium-Catalyzed, ortho-Selective C-H Halogenation of Benzyl Nitriles, Aryl Weinreb Amides, and Anilides

Das, Riki,Kapur, Manmohan

, p. 1114 - 1126 (2017)

A palladium-catalyzed, ortho-selective C-H halogenation methodology is reported herein. The highlight of the work is the highly selective C(sp2)-H functionalization of benzyl nitriles in the presence of activated C(sp3)-H bond, which results in good yields of the halogenated products with excellent regioselectivity. Along with benzyl nitriles, aryl Weinreb amides and anilides have been evaluated for the transformation using aprotic conditions. Mechanistic studies yield interesting aspects with respect to the pathway of the reaction and the directing group abilities.
