Check Digit Verification of cas no

The CAS Registry Mumber 128174-76-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,7 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128174-76:
(8*1)+(7*2)+(6*8)+(5*1)+(4*7)+(3*4)+(2*7)+(1*6)=135
135 % 10 = 5
So 128174-76-5 is a valid CAS Registry Number.

N-Arylphthalazinium Cations: Synthons for Biphthalazinylidenes via Endocyclic Phthalazinium Ylide Intermediates

Butler, Richard N.,Pyne, Carmel S.

, p. 3387 - 3390 (2007/10/02)

Treatment of 2-aryl-1-hydroxy-1,2-dihydrophthalazines with HClO4 in MeCN gave 2-N-arylphthalazinium cations as perchlorate salts.These, when heated with NaOAc in MeCN gave good yields of biphthalazinylidenes via an endocyclic 2-arylphthalazin-2-ium-1-ide
