The CAS Registry Mumber 343570-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,5,7 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 343570-76:
(8*3)+(7*4)+(6*3)+(5*5)+(4*7)+(3*0)+(2*7)+(1*6)=143
143 % 10 = 3
So 343570-76-3 is a valid CAS Registry Number.

HETEROCYCLIC AMIDINES : I. A ONE-STEP SYNTHESIS OF NEW α-SUBSTITUTED IMIDAZOLYLPHENYLACETIC ACIDS

Saturnino, Carmela,Abarghaz, Mustapha,Schmitt, Martine,Wermuth, Camille-Georges,Bourguignon, Jean-Jacques

, p. 1491 - 1502 (2007/10/02)

The reaction of α-phenyl-β-formylacrylic derivatives with various amidines (benzamidine, acetamidine) and heterocyclic amidines (2-aminopyridines, 3-aminopyridazines), yields α-substituted imidazolylphenylacetic acids and imidazoazines bearing a phenylacetic acid residue in position 3.Some mechanistic aspects of the cyclocondensation reaction will be discussed.
