34232-14-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34232-14-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,2,3 and 2 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 34232-14:
(7*3)+(6*4)+(5*2)+(4*3)+(3*2)+(2*1)+(1*4)=79
79 % 10 = 9
So 34232-14-9 is a valid CAS Registry Number.

ortho-Substituted Unsymmetrical Biaryls from Aryl tert-Butyl Sulfones
Clayden, Jonathan,Julia, Marc
, p. 1682 - 1683 (2007/10/02)
Nickel-catalysed coupling of arylmagnesium halides with aryl tert-butyl sulfones, and in particular with those bearing ortho-substituents introduced by ortholithiation, gives ortho-substituted unsymmetrical biaryls.
