733-88-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 733-88-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 733-88:
(5*7)+(4*3)+(3*3)+(2*8)+(1*8)=80
80 % 10 = 0
So 733-88-0 is a valid CAS Registry Number.

Equilibrium acidities of some sulfones and sulfoxides in tetrahydrofuran

Streitwieser, Andrew,Wang, George Peng,Bors, Daniel A.

, p. 10103 - 10112 (2007/10/03)

Ion pair acidities are reported in tetrahydrofuran (THF) solution for the lithium and cesium salts of several sulfones and one sulfoxide. These salts are shown to be monomeric in the THF solutions studied. Thermodynamic constants are reported for several salts. The results and some conductivity studies show that both the lithium and cesium salts are contact ion pairs in THF. Because of ion association the relative pKs are slightly lower for cesium salts and much lower for lithium salts than for the free ions in DMSO solution.
