Check Digit Verification of cas no
The CAS Registry Mumber 142779-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,7 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142779-55:
(8*1)+(7*4)+(6*2)+(5*7)+(4*7)+(3*9)+(2*5)+(1*5)=153
153 % 10 = 3
So 142779-55-3 is a valid CAS Registry Number.

Sonochemistry of Epoxyalkylhalides in the Presence of a Zinc-Copper Couple
Sarandeses, Luis A.,Mourino, Antonio,Luche, Jean-Louis
, p. 798 - 799 (1992)
Under sonication in aqueous ethanol, a zinc-copper induces the conjugated addition of epoxyalkyl groups to electron deficient alkenes in synthetically useful yields, provided that the two reducible functionalities are sufficiently far apart; 3,4-epoxyalky
