340167-06-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 340167-06-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,0,1,6 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 340167-06:
(8*3)+(7*4)+(6*0)+(5*1)+(4*6)+(3*7)+(2*0)+(1*6)=108
108 % 10 = 8
So 340167-06-8 is a valid CAS Registry Number.

Synthesis of new γ- and δ-lactones by acid cyclization of 2,4-diethylenic-diacids
Valla,Andriamialisoa,Zentz,Prat,Laurent,Giraud
, p. 279 - 282 (2001)
We have developed an easy synthesis for new γ- and δ-lactones. Acid-catalyzed cyclization of 2,4-diethylenic-diacids yields new γ or δ-lactones, depending on the substitution pattern of the unsaturated side chain.
