1201804-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1201804-80-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,1,8,0 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1201804-80:
(9*1)+(8*2)+(7*0)+(6*1)+(5*8)+(4*0)+(3*4)+(2*8)+(1*0)=99
99 % 10 = 9
So 1201804-80-9 is a valid CAS Registry Number.

Page/Page column 13, (2009/12/27)
Polyfluorene polymers and copolymers having substantial amounts (10-100%) of fluorenes coupled at the 2 and 5 positions of fluorene are useful as active layers in OLED devices where triplet energies >2.10 eV are required.
