Check Digit Verification of cas no

The CAS Registry Mumber 204203-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,2,0 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 204203-12:
(8*2)+(7*0)+(6*4)+(5*2)+(4*0)+(3*3)+(2*1)+(1*2)=63
63 % 10 = 3
So 204203-12-3 is a valid CAS Registry Number.

Highly active iron and cobalt catalysts for the polymerization of ethylene [18]

Small,Brookhart,Bennett

, p. 4049 - 4050 (2008/10/08)

Using the previously examined Ni(II) and Pd(II) α-diimine catalysts as a guide, new iron(II) and cobalt(II) catalysts based on tridentate pyridine bis-mine ligands were prepared. The resulting catalysts are robust and extremely active for polymerization of ethylene to linear, high-density polyethylene.
