Check Digit Verification of cas no

The CAS Registry Mumber 22115-43-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,1 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 22115-43:
(7*2)+(6*2)+(5*1)+(4*1)+(3*5)+(2*4)+(1*3)=61
61 % 10 = 1
So 22115-43-1 is a valid CAS Registry Number.

Cyclization Reactions of 2,3-Bis(2-cyanophenyl)propionitriles. III. Substituent Effect on the Carboanion Reactivities of the Propionitriles and Tautomerism of 5-Acetamido-11-cyanoindenoisoquinolines

Ando, Kazuo,Tokoroyama, Takashi,Kubota, Takashi

, p. 2885 - 2890 (2007/10/02)

The substituent effect in the base-catalyzed cyclization reaction of 2,3-bis(2-cyanophenyl)propionitriles (1) to 5-amino-11-cyano-11H-indenoisoquinolines has been studied and the result is discussed in terms of the dichotomic carbanion reactivities
