Check Digit Verification of cas no

The CAS Registry Mumber 49681-65-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,8 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 49681-65:
(7*4)+(6*9)+(5*6)+(4*8)+(3*1)+(2*6)+(1*5)=164
164 % 10 = 4
So 49681-65-4 is a valid CAS Registry Number.

Mass-spectrometric Determination of the Enthalpies of Formation of Chromium Chloride and Oxide Chloride Molecules

Milushin, M. I.,Gorokhov, L. N.

, p. 387 - 388 (2007/10/02)

Molecules of CrCl and ClCrO have been observed by the Knudsen effusion method with mass-spectrometric detection in the vapour over chromium oxide after adding barium chloride vapour.The isomolecular equilibria involving these molecules have been studied, and their ionisation potentials and enthalpies of formation have been determined.
