Check Digit Verification of cas no

The CAS Registry Mumber 1037396-94-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,7,3,9 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1037396-94:
(9*1)+(8*0)+(7*3)+(6*7)+(5*3)+(4*9)+(3*6)+(2*9)+(1*4)=163
163 % 10 = 3
So 1037396-94-3 is a valid CAS Registry Number.

Solvent-free synthesis of nitrones in a ball-mill

Colacino, Evelina,Nun, Pierrick,Colacino, Francesco Maria,Martinez, Jean,Lamaty, Frédéric

, p. 5569 - 5576 (2008/09/21)

Various C-aryl and C-alkyl-nitrones were synthesized within 0.5-2 h via condensation of an equimolar amount of aldehydes and N-substituted-hydroxylamines under solvent-free conditions in?a ball-mill apparatus. Reactions can be performed without the need of excluding air and moisture and yields the expected products with no need for further purification. The study has been complemented by Differential Scanning Calorimetry (DSC) and solid-state 13C MAS nuclear magnetic resonance experiments. We have also studied the temperature profile during the reaction. A comparative study with the corresponding solvent-free microwave activated reaction showed the superiority of the ball-milling method; 31 examples are described, including the synthesis of the anti-aging agent C-phenyl-N-tert-butyl nitrone (PBN) and one of its analogues C-2-pyridyl-N-tert-butylnitrone (2-PyBN).
