Check Digit Verification of cas no

The CAS Registry Mumber 27916-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,9,1 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 27916-98:
(7*2)+(6*7)+(5*9)+(4*1)+(3*6)+(2*9)+(1*8)=149
149 % 10 = 9
So 27916-98-9 is a valid CAS Registry Number.

Process for the arylation of olefines

-

, (2008/06/13)

A process for arylating an olefinic compound by addition of an aryl group to a double bond of said olefinic compound consisting in diazotizing an arylamine in an aqueous acidic solution comprising a lower alkanoic acid to form a solution of an aryldiazonium salt and reacting said aryldiazonium salt solution with an olefinic compound in an organic solvent in the presence of a catalytically effective amount of a copper halide. The amount of alkanoic acid is about 15 to 37% by volume of the total solvents used. The alkanoic acid is preferably acetic acid and the copper halide cuprous chloride.
