Check Digit Verification of cas no

The CAS Registry Mumber 1440519-61-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,5,1 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1440519-61:
(9*1)+(8*4)+(7*4)+(6*0)+(5*5)+(4*1)+(3*9)+(2*6)+(1*1)=138
138 % 10 = 8
So 1440519-61-8 is a valid CAS Registry Number.

Synthesis of isoindolinones via inverse-electron demand Diels-Alder cycloadditions

Huntley, Raymond J.,Gurram, Mahender,Walker, Joel R.,Jenkins, David M.,Robé, Emmanuel J.,Ahmed, Feryan

, p. 2286 - 2289 (2014/04/17)

A new synthetic method has been developed for the synthesis of 2,4,5-substituted isoindolinones by means of intramolecular inverse-electron demand Diels-Alder cycloaddition reactions of substituted pyridazines. By taking advantage of the inherent reactivity of an intermediate chloropyridazine, a diverse set of analogues were prepared from common reagents and intermediates.
