Check Digit Verification of cas no

The CAS Registry Mumber 85345-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,3,4 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 85345-99:
(7*8)+(6*5)+(5*3)+(4*4)+(3*5)+(2*9)+(1*9)=159
159 % 10 = 9
So 85345-99-9 is a valid CAS Registry Number.

SYNTHESIS OF 2-FLUOROPROPENOIC ACID DERIVATIVES

Tolman, Vladimir,Spronglova, Pavla

, p. 319 - 326 (2007/10/02)

A method is described for the synthesis of 2-fluoropropenoic acid esters, amides, and nitrile from the corresponding derivatives of 2-fluoro-3-(4-toluenesulfonyloxy)propanoic acid by heating with potassium phtalimide in vacuo.The free acid Ia and its chloride have also been synthetized.The reactivity of esters and nitrile of acid Ia has been verified by the Michael addition of diethyl acetamidomalonate to these compounds.
