Check Digit Verification of cas no

The CAS Registry Mumber 4210-46-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,1 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4210-46:
(6*4)+(5*2)+(4*1)+(3*0)+(2*4)+(1*6)=52
52 % 10 = 2
So 4210-46-2 is a valid CAS Registry Number.

Synthesis and magnetic properties of some crystalline nitroxide radicals

Griesar,Soto-Bustamante,Haase

, p. 567 - 575 (2007/10/03)

The syntheses of different nitroxide radicals are reported. The thermal behaviour of the nitroxide radicals was examined by polarizing microscopy, differential scanning calorimetry as well as X-ray diffraction experiments. Temperature dependent magnetic susceptibility measurements were carried out in order to determine the magnetic properties of these nitroxide radicals. The majority of the radicals presented here show weak antiferromagnetic exchange interactions.
