144433-90-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144433-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,3 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144433-90:
(8*1)+(7*4)+(6*4)+(5*4)+(4*3)+(3*3)+(2*9)+(1*0)=119
119 % 10 = 9
So 144433-90-9 is a valid CAS Registry Number.

Perthienyl anaolgues of Chichibabin's hydrocarbon. A new stable, highly amphoteric multistage redox system with low oxidation potentials

Kawase,Ueno,Oda

, p. 5405 - 5408 (1992)

Perthienyl analogues of Chichibabin's hydrocarbon have been first synthesized as fairly stable substances, showing highly amphoteric multistage redox properties with considerably low oxidation potentials.

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
