Check Digit Verification of cas no

The CAS Registry Mumber 83313-84-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,1 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83313-84:
(7*8)+(6*3)+(5*3)+(4*1)+(3*3)+(2*8)+(1*4)=122
122 % 10 = 2
So 83313-84-2 is a valid CAS Registry Number.

Unusual Products from the Reactions of Anhydrous Hydrogen Chloride with Arylacetylenes

Griesbaum, Karl,Rao, V. V. Ramana,Leifker, Gregor

, p. 4975 - 4981 (1982)

Liquid-phase reactions of anhydrous hydrogen chloride with p-methyl-, p-methoxy-, p-fluoro-, and unsubstituted phenylacetylene afforded cyclic trimers, tetramers, and pentamers of the corresponding arylacetylenes.Phenylacetylene gave additionally 1-methyl-1-phenyl-3-chloroindene.The reactions proceeded via the corresponding HCl diadducts, i.e., via 1-aryl-1,1-dichloroethanes as intermediates.
