Check Digit Verification of cas no

The CAS Registry Mumber 143673-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,6,7 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 143673-98:
(8*1)+(7*4)+(6*3)+(5*6)+(4*7)+(3*3)+(2*9)+(1*8)=147
147 % 10 = 7
So 143673-98-7 is a valid CAS Registry Number.

The Synthesis of Poly and Characterizations of Reaction with Nitrogen Dioxide

Ren, Jingzhu,Sakakibara, Kazuhisa,Hirota, Minoru

, p. 1897 - 1902 (2007/10/02)

Polymer-supported spin trap, poly (polyPBN), was prepared by using p-chlorostyrene as a starting material, followed by Grignard reaction, condensation with t-butylamine, reduction, polymerization, and oxidation.The adsorption ability of No2 by polyPBN was investigated in a closed-circulation system.PolyPBN maintains its original NO2 adsorbing ability in the mixed gas of nitrogen and nitrogen dioxide saturated with water vapor even after repeated (5 times) use.However, when the gaseous phase is freed from water, polyPBN exhibits less efficiency to adsorb NO2 and its adsorbing ability decreases gradually with the repeated use.
