Check Digit Verification of cas no

The CAS Registry Mumber 69718-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,7,1 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 69718-04:
(7*6)+(6*9)+(5*7)+(4*1)+(3*8)+(2*0)+(1*4)=163
163 % 10 = 3
So 69718-04-3 is a valid CAS Registry Number.

ALKALINE METAL FLUORIDES IN GRAPHITE - NEW CATALYSTS IN ORGANIC SYNTHESIS. I. REACTIONS OF POLYFLUOROAROMATIC COMPOUNDS WITH O- AND N-NUCLEOPHILIC AGENTS

Aksenov, V. V.,Vlasov, V. M.,Danilkin, V. I.,Rodionov, P. P.,Shnitko, G. N.

, p. 57 - 73 (2007/10/02)

The paper reports the use of new catalysts - alkaline metal fluorides in graphite of the general formula C8MF, where M=Li, Na, K, Rb or Cs, in the reactions of polyfluoroaromatic compounds with aromatic OH-acids and piperidine.These compounds are shown to have a high activity in the above processes, exceeding that of similar free fluorides of alkaline metals.
