74889-29-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74889-29-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,8 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74889-29:
(7*7)+(6*4)+(5*8)+(4*8)+(3*9)+(2*2)+(1*9)=185
185 % 10 = 5
So 74889-29-5 is a valid CAS Registry Number.

Products from N-Substituted Pyrroles and Trifluoroacetic Anhydride: Ratios and Conformations of Isomers

Chadwick, Derek J.,Meakins, G. Denis,Rhodes, Caroline A.

, p. 878 - 886 (2007/10/02)

A series of N-substituted pyrroles has been treated with trifluoroacetic anhydride.Small alkyl groups or aryl groups (as the N-substituents) lead exclusively, or almost exclusively, to the 2-trifluoroacetyl derivatives, bulky groups (notably 1-adamantyl) to the 3-derivatives, and those of intermediate size (such as i-propyl) to mixtures of isomers.N-Substituted 3-trifluoroacetylpyrroles exist in solution as mixtures of rotational isomers whereas the 2-isomers adopt a preferred conformation in which the nitrogen and oxygen atoms are in the syn orientation.
