Check Digit Verification of cas no

The CAS Registry Mumber 1173659-29-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,6,5 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1173659-29:
(9*1)+(8*1)+(7*7)+(6*3)+(5*6)+(4*5)+(3*9)+(2*2)+(1*9)=174
174 % 10 = 4
So 1173659-29-4 is a valid CAS Registry Number.

Phosphanyl ureas as ligands for ethylene oligomerization: A cascade reaction

Kuehl, Olaf,Lobitz, Peter,Peulecke, Normen

, p. 2777 - 2783 (2008)

The phosphanyl urea ligands MeNHC(O)NMePR2 (1: R = Ph and 2: R = 2,4-tBu2C6H3O) form effective ethylene oligomerization catalysts with [Ni(cod)2] (cod = 1,5 cyclooctadiene). Whereas the primary product with 1 is butene, 2 initiates a cascade reaction leading to hexenes and octenes. In the first reaction cycle ethylene is dimerized to butene, which serves as feedstock for the second dimerization cycle to the final products hexenes and octenes.
