209664-06-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 209664-06-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,6,6 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 209664-06:
(8*2)+(7*0)+(6*9)+(5*6)+(4*6)+(3*4)+(2*0)+(1*6)=142
142 % 10 = 2
So 209664-06-2 is a valid CAS Registry Number.

Polyphenylbiphenyls and polyphenylfluorenes
Tong, Ling
, p. 6000 - 6006 (2007/10/03)
A series of highly congested polyphenylbiphenyls and polyarylfluorenes has been prepared and their X-ray structures determined. Decaphenylbiphenyl adopts a very unusual C1-symmetric geometry (rather than the more intuitive D2 geometr
