Check Digit Verification of cas no

The CAS Registry Mumber 88682-86-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,6,8 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 88682-86:
(7*8)+(6*8)+(5*6)+(4*8)+(3*2)+(2*8)+(1*6)=194
194 % 10 = 4
So 88682-86-4 is a valid CAS Registry Number.

Transition Metal Carbene Complexes, CXXXII. Synthesis of Novel Gold(I)- and Gold(III) Carbene Complexes

Fischer, Ernst Otto,Boeck, Manfred,Aumann, Rudolf

, p. 3618 - 3623 (2007/10/02)

Pentacarbonyl complexes of chromium(0) (1a), molybdenum(0) (1b), and tungsten(0) (1c) react with chloroauric acid to give chlorogold(I) (2) and trichlorogold(III) (3), while the reaction of 1c with bromoauric acid yields only bromogold(I) (4).Tribromogold(III) (5) is obtained either from 4 by oxidative addition of bromine or from 3 by halogene substitution with boron tribromide. triiodogold(III) (6) is prepared by further halogene substitution from 5 with boron triiodide; it is reduced with sodium thiosulfate to give iodogold(I) (7).
