206346-79-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 206346-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,3,4 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 206346-79:
(8*2)+(7*0)+(6*6)+(5*3)+(4*4)+(3*6)+(2*7)+(1*9)=124
124 % 10 = 4
So 206346-79-4 is a valid CAS Registry Number.

Synthesis of 1,1-difluoroalkenes via α,α-difluoro-β-lactones
Ocampo, Rogelio,Dolbier, William R.,Paredes, Rodrigo
, p. 41 - 50 (2007/10/03)
A new method for the general synthesis of 1,1-difluoroalkenes from ketones is presented.The procedure involves initial condensation of a ketone with the difluoro Reformatsky reagent, hydrolysis to form the α,α-difluoro-β-hydroxy acids, followed by cycliza
