78739-49-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78739-49-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,7,3 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78739-49:
(7*7)+(6*8)+(5*7)+(4*3)+(3*9)+(2*4)+(1*9)=188
188 % 10 = 8
So 78739-49-8 is a valid CAS Registry Number.

Zinc Chloride Catalyzed Addition Reactions of Propargyl Chlorides with Acyclic 1,3-Dienes
Mayr, Herbert,Klein, Herbert
, p. 4097 - 4100 (2007/10/02)
Zinc chloride catalyzed reactions of propargyl chlorides with acyclic 1,3-dienes (at -78 deg C) give linear addition products, which cyclize to 4-(chloroalkylidene)cyclohexenes at elevated temperature.
