Check Digit Verification of cas no
The CAS Registry Mumber 4749-35-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,4 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4749-35:
(6*4)+(5*7)+(4*4)+(3*9)+(2*3)+(1*5)=113
113 % 10 = 3
So 4749-35-3 is a valid CAS Registry Number.

HALOGENATION OF UNSATURATED ESTERS-II. ADDITION OF Cl2, BrCl AND Br2 TO METHYL ESTERS OF MONOCHLOROPROPENOIC ACIDS
Pitkaenen, Maija,Korhonen, Ilpo O. O.
, p. 3367 - 3372 (2007/10/02)
The addition of chlorine, bromine chloride and bromine to methyl 2-chloropropenoate 1, methyl cis-3-chloropropenoate 2 and methyl trans-3-chloropropenoate 3 under ionic and radical conditions gave regioisomer mixtures.Both trans- and cis-addition of halogen species was observed, bromine preferentially adding to the non-halogenated carbon atom.
