204399-37-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 204399-37-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,3,9 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 204399-37:
(8*2)+(7*0)+(6*4)+(5*3)+(4*9)+(3*9)+(2*3)+(1*7)=131
131 % 10 = 1
So 204399-37-1 is a valid CAS Registry Number.

Synthesis of fluorinated enynes and dienes via 1-bromo 2-fluoro alkenes
Eddarir,Mestdagh,Rolando
, p. 69 - 72 (2007/10/02)
A stereospecific synthesis of fluorinated enynes and dienes was performed through palladium-catalyzed condensation of 1-bromo-2-fluoroalkenes, synthesized either through 'BrF' addition to the corresponding alkynes or through bromine addition and HBr elimi
