Check Digit Verification of cas no

The CAS Registry Mumber 1201934-84-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,1,9,3 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1201934-84:
(9*1)+(8*2)+(7*0)+(6*1)+(5*9)+(4*3)+(3*4)+(2*8)+(1*4)=120
120 % 10 = 0
So 1201934-84-0 is a valid CAS Registry Number.

Two-directional approach for the rapid synthesis of 2,4-bis-aminoaryl pyridine derivatives

Morgentin, Remy,Barlaam, Bernard,Foote, Kevin,Hassall, Lorraine,Hawkins, Janet,Jones, Clifford D.,Le Griffon, Antoine,Peru, Aurelien,Ple, Patrick

We have developed two different approaches in parallel to rapidly access 2,4-bis aminoaryl pyridine compounds from a common starting material. The C-4/C-2 approach uses palladium-mediated coupling reactions to sequentially functionalize C-4 and then C-2. An alternative C-2/C-4 route uses a regioselective SNAr reaction to first substitute at C-2 then subsequently at C-4 by a palladium-mediated reaction. Both approaches have been used successfully to provide a range of 2,4-bis-aminoaryl pyridine compounds.
