99942-78-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99942-78-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,4 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99942-78:
(7*9)+(6*9)+(5*9)+(4*4)+(3*2)+(2*7)+(1*8)=206
206 % 10 = 6
So 99942-78-6 is a valid CAS Registry Number.

Amidines. Part 15. Influence of Substitution at Imino and Amino Nitrogen Atoms on pKa Values of N1-Methyl-N1N2-diarylacetamidines

Raczynska, Ewa,Oszczapowicz, Janusz,Walczak, Malgorzata

, p. 1087 - 1090 (2007/10/02)

A series of 19 unreported N1-methyl-N1N2-diarylacetamidines containing two different substituents at the phenyl rings have been synthesized and their pKa values in 95.6percent ethanol (azeotrope) measured.The pKa values have been correlated with ?0 constants of the two substituents.The influence of substitution at either of the nitrogen atoms on basicity and on the regression coefficient is discussed, and it is shown that the pKa values of N1N2-diarylamidines can be predicted with satisfactory accuracy on the basis of the dual-substituent (planar) Hammett equation.
