Check Digit Verification of cas no

The CAS Registry Mumber 675200-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,5,2,0 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 675200-39:
(8*6)+(7*7)+(6*5)+(5*2)+(4*0)+(3*0)+(2*3)+(1*9)=152
152 % 10 = 2
So 675200-39-2 is a valid CAS Registry Number.

-

Page/Page column 34-35, (2010/02/06)

The invention relates to compounds, in which a transition metal comprising at least two ligand systems is complexed and at least two of said systems are reversibly linked to one another by at least one bridge consisting of a donor and an acceptor, whereby at least one fluorenyl ligand is included and at least one substituent of the acceptor group is an alkyl or aryl radical. The invention also relates to the use of said compounds with donor-acceptor interaction as polymerisation catalysts for producing high-molecular elastomers.
