Check Digit Verification of cas no

The CAS Registry Mumber 18925-68-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,2 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18925-68:
(7*1)+(6*8)+(5*9)+(4*2)+(3*5)+(2*6)+(1*8)=143
143 % 10 = 3
So 18925-68-3 is a valid CAS Registry Number.

Correlation of the rates of solvolysis of phenyl chloroformate

Kevill, Dennis N.,D'Souza, Malcolm J.

, p. 1721 - 1724 (1997)

The specific rates of solvolysis of phenyl chloroformate in 21 solvents can be very well correlated using the extended Grunwald-Winstein equation, with incorporation of the NT solvent nucleophilicity scale and the YCl solvent ionizing scale, with sensitivities towards changes in the scale having values of 1.68 ± 0.10 and 0.57 ± 0.06, respectively. This is a solvolysis which, on the basis of several other types of evidence, is believed to follow an addition-elimination pathway with addition being rate-determining (or possibly an enforced concerted variant), and these sensitivities can be considered to be representative values for chloroformate esters following such a pathway.
