90788-47-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90788-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,8 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90788-47:
(7*9)+(6*0)+(5*7)+(4*8)+(3*8)+(2*4)+(1*7)=169
169 % 10 = 9
So 90788-47-9 is a valid CAS Registry Number.

Synthesis of 3-Phenylisoquinolones by Reaction of Simple Pyrroline-2,3-diones with Benzyne. New Mechanistic Considerations
Cobas, Agustin,Guitian, Enrique,Castedo, Luis
, p. 3113 - 3117 (2007/10/02)
3-Phenylisoquinolones were obtained by cycloaddition of benzyne to 5-phenylpyrroline-2,3-diones.New mechanistic hypotheses for these transformations are discussed.
