Check Digit Verification of cas no

The CAS Registry Mumber 23433-02-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,4,3 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23433-02:
(7*2)+(6*3)+(5*4)+(4*3)+(3*3)+(2*0)+(1*2)=75
75 % 10 = 5
So 23433-02-5 is a valid CAS Registry Number.

Relationship of Structure to Properties in Surfactants. 9. Syntheses and Properties of 1,2- and 1,3-Alkanediols

Kwan, Chang-Chin,Rosen, Milton J.

, p. 547 - 551 (2007/10/02)

A number of 1,2- and 1,3-alkanediols containing 10-15 carbon atoms in the alkyl group have been synthesized, purified, and characterized.Surface tension measurements on aqueous solutions of these compounds at 25 deg C have been used to calculate surface excess concentration, area/molecule at the aqueous solution/air interface, critical micelle concentration, efficiency and effectiveness of surface tension reduction, and standard free energy of adsorption and of micellization.The compounds appear to be adsorbed at the aqueous solution/air interface in an almost close-packed arrangement with both hydroxyl groups lying in the interface and with the alkyl chain oriented perpendicular to it.The data indicate that, in its surface properties in aqueous solution, a 1,3-alkanediol is very similar to a 1,2-alkanediol with one less carbon atom.The standard free energy of adsorption of the HOCH2CHOH- or HOCH2CH2CHOH- group at the aqueous solution/air interface is 4.3-5.2 kJ mol-1, whereas the standard free energy of micellization of these groups in aqueous solution is 10.3-10.9 kJ mol-1.
