344864-68-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344864-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,8,6 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 344864-68:
(8*3)+(7*4)+(6*4)+(5*8)+(4*6)+(3*4)+(2*6)+(1*8)=172
172 % 10 = 2
So 344864-68-2 is a valid CAS Registry Number.

β-ethoxycarbonyl β, γ-insaturated γ-lactones 2 are easily prepared by dehydration of β-acyl β-ethoxycarbonyl α-alkyl propionic acids.Otherwise the condensation of these acids with allylzinc reagents produces β-ethoxycarbonyl γ-lactones 3 with a β-ethyleni
