Check Digit Verification of cas no

The CAS Registry Mumber 444989-59-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,9,8 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 444989-59:
(8*4)+(7*4)+(6*4)+(5*9)+(4*8)+(3*9)+(2*5)+(1*9)=207
207 % 10 = 7
So 444989-59-7 is a valid CAS Registry Number.

Mono-aromatic ring-fused versus adjacently di-aromatic ring-fused tetraazaporphyrins: Regioselective synthesis and their spectroscopic and electrochemical properties

Kobayashi, Nagao,Fukuda, Takamitsu

, p. 8021 - 8034 (2002)

A method which preferentially produces adjacently di-aromatic ring-substituted tetraazaporphyrins (TAPs) has been developed, and their electrochemical and spectroscopic properties have been studied and compared with those of the corresponding series of mo
