Check Digit Verification of cas no
The CAS Registry Mumber 693-33-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 693-33:
(5*6)+(4*9)+(3*3)+(2*3)+(1*3)=84
84 % 10 = 4
So 693-33-4 is a valid CAS Registry Number.

The Effects of Zwitterionic Surfactant Systems upon Aromatic Nucleophilic Substitution
Cipiciani, Antonio,Primieri, Stefania
, p. 1365 - 1367 (2007/10/02)
Reactions of OH(-) with 4-chloro-3,5-dinitrobenzoic acid (1) and 2-chloro-3,5-dinitrobenzoic acid (2) have been examined in solutions of N,N-dimethyl-N-tetradecylglycine (DTG) and N,N-dimethyl-N-hexadecylglycine (DHG).DTG and DHG ihibit hydroxydehalogenation of (1) and kinetic profiles for this reaction tend towards a plateau which assumes different values depending on the pH; hence the inhibition does not stop the reaction.Reactions of (2) with OH(-) in the presence of DTG and DHG exhibit a 'non-effect'.The important factor underlying this difference of behaviour between (1) and (2) in the presence of zwitterionic surfactants is probably the orientation of the substrates within the microaggregates.
