Check Digit Verification of cas no

The CAS Registry Mumber 229031-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,0,3 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 229031-55:
(8*2)+(7*2)+(6*9)+(5*0)+(4*3)+(3*1)+(2*5)+(1*5)=114
114 % 10 = 4
So 229031-55-4 is a valid CAS Registry Number.

Cross coupling of vinyl triflates and alkyl Grignard reagents catalyzed by niekel(0)-complexes

Busacca, Carl A.,Eriksson, Magnus C.,Fiaschi, Rita

, p. 3101 - 3104 (2007/10/03)

The scope and limitations of the Nickel(0)-catalyzed cross coupling of vinyl triflates with alkyl Grignard reagents have been studied. The effect of triflate substitution, solvent, and especially ligands have been examined. Ligands which are successful for sp2 and sp Grignard reagents fail for sp3 Grignard reagents.
