Check Digit Verification of cas no

The CAS Registry Mumber 1325725-29-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,5,7,2 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1325725-29:
(9*1)+(8*3)+(7*2)+(6*5)+(5*7)+(4*2)+(3*5)+(2*2)+(1*9)=148
148 % 10 = 8
So 1325725-29-8 is a valid CAS Registry Number.

Synthesis and electronic properties of an azulene-fused tribenzotetraazaporphyrin

Muranaka, Atsuya,Yonehara, Mitsuhiro,Hirayama, Machiko,Saito, Asami,Kobayashi, Nagao,Uchiyama, Masanobu

, p. 714 - 716 (2011)

A novel tribenzotetraazaporphyrin with a fused azulene ring was synthesized via mixed condensation reaction of 5,6-dicyanoazulene and 3,6- dibutoxyphthalonitrile. The macrocycle exhibited several intense absorption peaks from 600 to 900 nm. The spectroscopic properties were analyzed by DFT calculations.
