Check Digit Verification of cas no
The CAS Registry Mumber 649-65-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 649-65:
(5*6)+(4*4)+(3*9)+(2*6)+(1*5)=90
90 % 10 = 0
So 649-65-0 is a valid CAS Registry Number.

"HALF-OPEN COBALTOCENE" CHEMISTRY: DIENE REPLACEMENT VS. HYDRIDE ABSTRACTION BY THE TRIPHENYLMETHYL CATION
Newbound, Timothy D.,Ernst, Richard D.
, p. 213 - 220 (2007/10/02)
Cyclopentadienyl(η4-2,4-bis(trifluoromethyl)-1,3-pentadiene)cobalt has been prepared by the reaction of the fluorinated diene with (cyclopentadienyl)bis(ethylene)cobalt.An attempt to bring about hydride abstraction from the former compound using the triphenylmethyl cation has instead led to a replacement of the fluorinated diene by an η5-(C6H5)3C(1+) ligand.
