149367-74-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149367-74-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,3,6 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 149367-74:
(8*1)+(7*4)+(6*9)+(5*3)+(4*6)+(3*7)+(2*7)+(1*4)=168
168 % 10 = 8
So 149367-74-8 is a valid CAS Registry Number.

Synthesis of precursor molecules for low band gap polymers
Hanack,Schmid,Echinger,Teichert,Hieber
, p. 634 - 642 (2007/10/02)
The synthesis and characterization of precursors for polyarene- and hetarenemethylenes (PAM) of structure 3, which are predicted to be low band gap polymers are described. The precursor molecules 4 are synthesized from the corresponding 2-thiophene- and 2
