164933-39-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 164933-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,9,3 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 164933-39:
(8*1)+(7*6)+(6*4)+(5*9)+(4*3)+(3*3)+(2*3)+(1*9)=155
155 % 10 = 5
So 164933-39-5 is a valid CAS Registry Number.

Enantioselective synthesis of three insect pheromones, (5Z, 13S)-5-tetradecen-13-olide, (9R)-decan-9-olide, and (S)-2-acetoxytridecane, has been achieved by using Mn-salen catalyzed asymmetric epoxidation as a key step.
