Check Digit Verification of cas no

The CAS Registry Mumber 20851-90-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,5 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20851-90:
(7*2)+(6*0)+(5*8)+(4*5)+(3*1)+(2*9)+(1*0)=95
95 % 10 = 5
So 20851-90-5 is a valid CAS Registry Number.

B12-TiO2 hybrid catalyst for dehalogenation of organic halides

Shimakoshi, Hisashi,Sakumori, Emiko,Kaneko, Kenji,Hisaeda, Yoshio

, p. 468 - 469 (2009)

A cobalamin derivative, cobyrinie acid, was effectively immobilized on TiO2, and the hybrid TiO2 was characterized by UV-vis, XPS, MALDI-TOFMS as well as TEM analysis. The hybrid TiO2 exhibits high reactivity for dehalogenation of various organic halides such as phenethyl bromide, benzyl bromide, and 1,1-bis(4-chlorophenyl)-2,2,2-trichloroethane (DDT) under irradiation with UV light at room temperature.
