Check Digit Verification of cas no

The CAS Registry Mumber 668985-82-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,8,9,8 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 668985-82:
(8*6)+(7*6)+(6*8)+(5*9)+(4*8)+(3*5)+(2*8)+(1*2)=248
248 % 10 = 8
So 668985-82-8 is a valid CAS Registry Number.

Synthesis and characterization of 2-imino-indole nickel complexes and their ethylene oligomerization study

Li, Jitai,Gao, Tielong,Zhang, Wen,Sun, Wen-Hua

, p. 1372 - 1374 (2003)

A series of 2-imino-indole derivatives and their neutral nickel complexes were synthesized and characterized. A single-crystal X-ray analysis of [Ni(C10H7)(C18H16ClN 2)(PPh3)] shows the nickel center adopted a square-planar coordination geometry. The nickel complexes act solely as effective catalysts for ethylene oligomerization with the activity up to 2.05 × 10 4 g ethylene mol-1 h-1.
