Check Digit Verification of cas no

The CAS Registry Mumber 98859-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,8,5 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98859-22:
(7*9)+(6*8)+(5*8)+(4*5)+(3*9)+(2*2)+(1*2)=204
204 % 10 = 4
So 98859-22-4 is a valid CAS Registry Number.

Electrophilic Substitution in (Arene)tricarbonylchromium Complexes. Part 1.

von Rosenberg, Joseph L.,Pinder, A. Reginald

, p. 747 - 752 (1987)

The Friedel-Crafts acetylation of several (arene)tricarbonylchromium complexes have been investigated.From the results it is concluded that the tricarbonylchromium group deactivates to a small extent towards electrophilic substitution the ring to which it is attached.In the case of tricarbonyl(diphenylmethane)chromium (1; n=1), however, attack occurred on both rings to about an equal extent, possible explanations for this unexpected behaviour are advanced.
