Check Digit Verification of cas no

The CAS Registry Mumber 467435-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,7,4,3 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 467435-33:
(8*4)+(7*6)+(6*7)+(5*4)+(4*3)+(3*5)+(2*3)+(1*3)=172
172 % 10 = 2
So 467435-33-2 is a valid CAS Registry Number.

Synthesis of new stable arylthiopyridinium N-arylimide zwitterions. Part 20: Fused azolium salts

Messmer, András,K?vér, Péter,Riedl, Zsuzsanna,G?m?ry, ágnes,Hajós, Gy?rgy

, p. 3613 - 3618 (2007/10/03)

3-Aryltetrazolopyridinium salts react with thiophenolates to afford stable arylthio substituted pyridinium N-arylimide zwitterions as red crystals. The angularly fused tetrazolo[1,5-a]quinolinium salt react analogously and also yielded a blue zwitterionic product. The new zwitterions underwent solvolysis in methanol to give N-anilinopyridones, their alkylation yielding stable N-alkyl substituted salts and their reaction with dipolarophiles results in the formation of stable cycloadducts.
