157761-89-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 157761-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,6 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 157761-89:
(8*1)+(7*5)+(6*7)+(5*7)+(4*6)+(3*1)+(2*8)+(1*9)=172
172 % 10 = 2
So 157761-89-2 is a valid CAS Registry Number.

Effective separation of single-walled carbon nanotubes and their very different electrochemical behaviours

Zhang, Xin,Chen, Lin,Chen, Xiang-Yu,Zhang, Hanzhi,Yang, Liuqing,Yang, Fengchun

, p. 9287 - 9290 (2016/07/25)

The electrochemical behaviors of m- and s-SWNTs obtained from as-prepared SWNTs using a novel binaphthyl based separation agent were studied. The s-SWNTs show higher capacitance but lower electrocatalytic activity, while m-SWNTs show the opposite. Their e

Prototypes for the polaronic ferromagnet. Synthesis and characterization of high-spin organic polymers

Murray, Michael M.,Kaszynski, Piotr,Kaisaki, David A.,Chang, Wonghil,Dougherty, Dennis A.

, p. 8152 - 8161 (2007/10/02)

Preparation and characterization of several new polymers (1-7) that are considered one-dimensional prototypes for the polaronic ferromagnet are reported. Synthesis involved either Wittig or Suzuki coupling to produce polymers with extended π systems. Oxid
