1254941-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1254941-69-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,9,4 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1254941-69:
(9*1)+(8*2)+(7*5)+(6*4)+(5*9)+(4*4)+(3*1)+(2*6)+(1*9)=169
169 % 10 = 9
So 1254941-69-9 is a valid CAS Registry Number.

Synthesis of hyperbranched poly(m-phenylene)s via suzuki polycondensation of a branched AB2 monomer
Xue, Zheng,Finke, Aaron D.,Moore, Jeffrey S.
, p. 9277 - 9282 (2010)
An efficient synthesis of hyperbranched poly(m-phenylene)s is achieved by Suzuki polycondensation of a m-terphenyl-derived branched AB2 monomer. The resulting hyperbranched polymers show high molecular weight and relatively low polydispersity a
