3320-33-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3320-33-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,2 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3320-33:
(6*3)+(5*3)+(4*2)+(3*0)+(2*3)+(1*3)=50
50 % 10 = 0
So 3320-33-0 is a valid CAS Registry Number.

Synthesis and properties of a millable polyurethane elastomer with low halloysite nanotube content

Gong, Bing,Ouyang, Chunfa,Yuan, Ye,Gao, Qun

, p. 77106 - 77114 (2015)

Nanocomposites comprised of millable polyurethane (MPU) and very low loadings of halloysite nanotubes (HNTs) have been prepared with high tensile strength and elongation at break, and cured using either toluene diisocyanate dimer or dicumyl peroxide as cr

experimental part, p. 1167 - 1170 (2012/01/06)

Several new asymmetric substituted dicarbamates were synthesized with a convenient route. Firstly, tolylene-2, 4-diisocyanate dimmer was obtained from monomer with tributylphosphine as catalyst. Then, the dimmer reacted with alcohol (R1OH) to p

Preparation, Characterization and Selective Reactions of Novel [1,3]Diazetidine-2,4-diones (Uretdiones) - A New Route to Generate Asymmetric Substituted Toluylenediisocyanate-Derivatives

Risch, Nikolaus,Westerwelle, Ulrich,Kiene, Jürgen,Keuper, Ralf

, p. 616 - 619 (2007/10/03)

The selective cyclodimerization of monomeric diisocyanates like IPDI 4 and TDI 5 yields [1,3]diazetidine-2,4-diones (uretdiones). On this basis, a new method for the selective transformation of the NCO-groups of asymmetric substituted diisocyanates is des
