Check Digit Verification of cas no
The CAS Registry Mumber 18973-22-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,7 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18973-22:
(7*1)+(6*8)+(5*9)+(4*7)+(3*3)+(2*2)+(1*2)=143
143 % 10 = 3
So 18973-22-3 is a valid CAS Registry Number.

The reduction of cobalt(III) by neptunium(V) and the neptunium(V)-chromium(III) complex
Sullivan, James C.,Thompson, Richard C.
, p. 1795 - 1798 (1967)
The rate law for the reaction Np(V) + Co(III) = Np(VI) + Co(II), from 5 to 25° in perchloric acid-lithium perchlorate solutions of constant ionic strength, is -d[Np(V)]/dt = k′[Np(V)] [Co(III)] where k′ = k0e-β[H+]. Under the same co
