Check Digit Verification of cas no

The CAS Registry Mumber 954416-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,4,4,1 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 954416-49:
(8*9)+(7*5)+(6*4)+(5*4)+(4*1)+(3*6)+(2*4)+(1*9)=190
190 % 10 = 0
So 954416-49-0 is a valid CAS Registry Number.

Rapid access to 3-(N-substituted)-aminoquinolin-2(1H)-ones using palladium-catalyzed C-N bond coupling reaction

Messaoudi, Samir,Audisio, Davide,Brion, Jean-Daniel,Alami, Mouad

, p. 10202 - 10210 (2007)

A series of 3-(N-substituted)-aminoquinolin-2(1H)-ones have been synthesized by the palladium-catalyzed C-N coupling reaction starting from 3-bromoquinolin-2-(1H)-ones. Various nucleophiles including amines, amides, sulfonamides, carbamates and ureas have been used successfully. In all the cases, the reactions take place rapidly in 1,4-dioxane and proceed in good to excellent yield using palladium acetate as a catalyst, Xantphos as a ligand and Cs2CO3 as a base.
