Check Digit Verification of cas no

The CAS Registry Mumber 93139-46-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,1,3 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 93139-46:
(7*9)+(6*3)+(5*1)+(4*3)+(3*9)+(2*4)+(1*6)=139
139 % 10 = 9
So 93139-46-9 is a valid CAS Registry Number.

Metal-free activation of C-C multiple bonds through halide ion pairs: Diels-Alder reactions with subsequent aromatization

Kaper, Helena,Antonietti, Markus,Goettmann, Frédéric

, p. 4546 - 4549 (2008)

Imidazolium and ammonium halides, both in homogeneous phase or immobilized on mesoporous silica, proved able to promote the aromatization reaction of Diels-Alder adducts under ethylene and H2 elimination. These observations point to the increased nucleophilicity of such halide ions. They also open the possibility to employ such ion pairs as nucleophilic organocatalysts, for example, as substitutes for phosphines or amines.
