Check Digit Verification of cas no

The CAS Registry Mumber 89894-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,9 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 89894-04:
(7*8)+(6*9)+(5*8)+(4*9)+(3*4)+(2*0)+(1*4)=202
202 % 10 = 2
So 89894-04-2 is a valid CAS Registry Number.

Structure of the t-butyl N-(4-chlorophenyl)thiooxamate and related complexes with heavy metals

Raouf-Benchekroun, Khadija,Bastide, Jean-Daniel,De Blic, Arnaud,Cazaux, Louis,Baltas, Michel

, p. 191 - 201 (1999)

The structure of the title thiooxamate was studied by molecular modeling and i.r spectroscopy along with its ZnBr2 complex and transformation products, thiooxamic acid and zinc thiooxamates. Similar results were obtained with heavy metal salts like Cd(II) and Hg(II) perchlorates with, moreover, formation constants determination of their complexes by ultra- violet spectrophotometry.
