266674-45-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 266674-45-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,6,6,7 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 266674-45:
(8*2)+(7*6)+(6*6)+(5*6)+(4*7)+(3*4)+(2*4)+(1*5)=177
177 % 10 = 7
So 266674-45-7 is a valid CAS Registry Number.

Cycloaromatization and DNA cleavage of novel non-conjugated aromatic enetetrayne systems
Ueda,Miyawaki,Sugane,Sakurai,Wada,Futai
, p. 192 - 195 (2007/10/03)
The novel, non-conjugated aromatic enetetrayne (2) underwent thermal cycloaromatization reaction to give polyphenylene derivative 6, forming a methyl cation as an active intermediate, and showed DNA-cleaving activity.
