Check Digit Verification of cas no

The CAS Registry Mumber 1213251-50-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,3,2,5 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1213251-50:
(9*1)+(8*2)+(7*1)+(6*3)+(5*2)+(4*5)+(3*1)+(2*5)+(1*0)=93
93 % 10 = 3
So 1213251-50-3 is a valid CAS Registry Number.

Mild and general method for the α-Arylation of heteroaromatic ketones

Desai, Lopa V.,Ren, Danan T.,Rosner, Thorsten

supporting information; experimental part, p. 1032 - 1035 (2010/06/15)

Chemical equation Presented The development of a general and mild method for Pd-catalyzed α-arylatlon of a variety of ketones bearing multiple heteroatoms Is described. The ligand to metal ratio and the position of the heteroatoms with respect to the carbonyl moiety significantly impact the efficiency of these transformations. In addition, these conditions were successfully applied to the α-arylation of cyclic imines. A detailed Investigation of the scope of this methodology, including the effect of the ligand to metal ratio, Is discussed.
