The CAS Registry Mumber 670256-65-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,0,2,5 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 670256-65:
(8*6)+(7*7)+(6*0)+(5*2)+(4*5)+(3*6)+(2*6)+(1*5)=162
162 % 10 = 2
So 670256-65-2 is a valid CAS Registry Number.

Formation of a Unique ansa-Metallocene Framework by Intramolecular Photochemical [2+2] Cycloaddition of Bis(2-alkenylindenyl)zirconium Complexes

Nie, Wan-Li,Erker, Gerhard,Kehr, Gerald,Froehlich, Roland

, p. 310 - 313 (2004)

Complexes with backbone: Upon photolysis the title complexes undergo intramolecular [2+2] cycloaddition to yield unique cyclobutylene-bridged ansa-zirconocenes. The annelated phenylene rings of the indenyl ligand lie directly above and below the σ ligands
