82874-32-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82874-32-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,7 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82874-32:
(7*8)+(6*2)+(5*8)+(4*7)+(3*4)+(2*3)+(1*2)=156
156 % 10 = 6
So 82874-32-6 is a valid CAS Registry Number.

Synthesis and structures of zwitterionic polymers to induce electrostatic interaction with PDMS surface treated by air-plasma

Tanaka, Mutsuo,Hirata, Yoshiki,Sawaguchi, Takahiro,Kurosawa, Shigeru

, p. 330 - 343 (2018)

Various zwitterionic polymers, sulfobetaine and phosphoryl choline derivatives were synthesized in order to investigate zwitterionic polymer structures toward surface modification of PDMS, where the adsorption of zwitterionic polymers on polydimethylsiloxane surface treated with air-plasma was induced by the electrostatic interaction,. The electrostatic interaction was evaluated with hydrophilicity. The results suggested that a sulfobetaine polymer with higher molecular weight, lower molecular weight distribution, and shorter alkyl chain afforded high electrostatic interaction. A sulfobetaine polymer bearing phenylazide group showed similar electrostatic interaction with the PDMS surface, and it is a promising material for surface modification ofpolydimethylsiloxane.
