Check Digit Verification of cas no

The CAS Registry Mumber 239807-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,9,8,0 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 239807-28:
(8*2)+(7*3)+(6*9)+(5*8)+(4*0)+(3*7)+(2*2)+(1*8)=164
164 % 10 = 4
So 239807-28-4 is a valid CAS Registry Number.

Reductive dehydroxy coupling of 2-(hydroxymethyl)indenes to prepare ethano-bridged bis(2-indenyl) ansa-titanocenes

Palandoken, Hasan,Wyatt, Justin K.,Hitchcock, Shawn R.,Olmstead, Marilyn M.,Nantz, Michael H.

, p. 338 - 347 (2007/10/03)

New examples of ansa-titanocenes derived from 1,2-bis(2-indenyl)ethane have been prepared. The titanium-mediated reductive coupling of 2-(hydroxymethyl)indenes provided a convenient method for substrate dimerization. Alkyl substitution of the indene ring at C(3) improved the regioselectivity of the reductive coupling to provide the ethylene bis(2-indenyl)ansa-ligands in 29-62% yield.
