129199-59-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129199-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,9 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129199-59:
(8*1)+(7*2)+(6*9)+(5*1)+(4*9)+(3*9)+(2*5)+(1*9)=163
163 % 10 = 3
So 129199-59-3 is a valid CAS Registry Number.

Synthesis of 8-Membered Ring Lactones from Dioxolenones
Petasis, Nicos A.,Patane, Michael A.
, p. 836 - 837 (2007/10/02)
Thermolysis of hydroxy-dioxolenones affords 8-membered ring β-keto-lactones, which may be suitable for the synthesis of naturally occuring 8-membered ring cyclic ethers.
