76739-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76739-71-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,3 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 76739-71:
(7*7)+(6*6)+(5*7)+(4*3)+(3*9)+(2*7)+(1*1)=174
174 % 10 = 4
So 76739-71-4 is a valid CAS Registry Number.

A highly diastereoselective synthesis of trichoverrol B (1) is described.Critical to the success of this work is the development of a method for esterification of (Z,E)-dienoic acid derivatives without olefin isomerisation.
