252255-19-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 252255-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,2,5 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 252255-19:
(8*2)+(7*5)+(6*2)+(5*2)+(4*5)+(3*5)+(2*1)+(1*9)=119
119 % 10 = 9
So 252255-19-9 is a valid CAS Registry Number.

Macrocyclic poly arylamines for rigid connection of poly radical cation spins
Selby, Trent D.,Blackstock, Silas C.
, p. 2053 - 2055 (2008/02/09)
matrix presented The synthesis of macrocyclic arylamines 3 and 4 is reported. These structures yield conformationally rigid polyradical cations for investigation of their electron spin properties. Dication 32+ has dual N and N′ connection of it
