Check Digit Verification of cas no

The CAS Registry Mumber 161680-06-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,6,8 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 161680-06:
(8*1)+(7*6)+(6*1)+(5*6)+(4*8)+(3*0)+(2*0)+(1*6)=124
124 % 10 = 4
So 161680-06-4 is a valid CAS Registry Number.

Intramolecular Pd(0)-catalyzed reactions of β-(2-iodoanilino) carboxamides: Enolate arylation and nucleophilic substitution at the carboxamide group

Sole, Daniel,Serrano, Olga

, p. 9372 - 9378 (2008)

(Chemical Equation Presented) Two different reaction pathways, the enolate arylation and the acylation of the aryl halide, can be promoted by a Pd(0) catalyst starting from β-(2-iodoanilino) carboxamides. The intramolecular acylation of β-(2-iodoanilino) carboxamides reported here is the first example of a nucleophilic attack of a σ-arylpalladium species at the carboxamide group, a framework that is usually inert toward organopalladium reagents.
