344886-79-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344886-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,8,8 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 344886-79:
(8*3)+(7*4)+(6*4)+(5*8)+(4*8)+(3*6)+(2*7)+(1*9)=189
189 % 10 = 9
So 344886-79-9 is a valid CAS Registry Number.

A NEW SYNTHESIS OF δ-LACTONES FROM OXETANES
Yamaguchi, Masahiko,Shibato, Keisuke,Hirao, Ichiro
, p. 1159 - 1162 (2007/10/02)
Oxetanes were reacted with lithium enolates generated from esters or amides in the presence of boron trifluoride etherate to give δ-hydroxyesters or amides in high yield, which were hydrolyzed and converted to δ-lactones.
