40227-55-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40227-55-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,2 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 40227-55:
(7*4)+(6*0)+(5*2)+(4*2)+(3*7)+(2*5)+(1*5)=82
82 % 10 = 2
So 40227-55-2 is a valid CAS Registry Number.

The Synthesis of Isoindolin-3-ones, Phthalazin-4(3H)-ones and Related Systems
Dunn, A.D.
, p. 961 - 964 (2007/10/02)
The reaction between methyl 2-cyanobenzoate and its pyridine analogues gave isoindolin-3-ones, phthalazin-4(3H)-ones and their corresponding aza analogues.Some reactions of 1-benzylaminoiminoisoindolin-3-one 5b were investigated.
