Check Digit Verification of cas no

The CAS Registry Mumber 142489-73-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,8 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142489-73:
(8*1)+(7*4)+(6*2)+(5*4)+(4*8)+(3*9)+(2*7)+(1*3)=144
144 % 10 = 4
So 142489-73-4 is a valid CAS Registry Number.

Matrix reaction of the oxygen atom with the CBrCl3 molecule Identification of phosgene complexes with Cl2 and Br2

Abdelaoui, O.,Schriver, L.,Schriver, A.

, p. 335 - 346 (1992)

FT-IR spectroscopy has been coupled with the matrix isolation technique to investigate the mechanism of the CBrCl3 photooxidation by ozone at 12 K by UV light.COCl2 is observed as the only primary product and CO as a secondary photolysis product.At 35 K warm up after photolysis generated phosgene complexes with Cl2 and Br2.Identification of these molecular complexes was performed with mixtures of laboratory synthesized phosgene with X (X=Cl2, Br2) trapped in argon matrices.
