Check Digit Verification of cas no
The CAS Registry Mumber 76893-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,8,9 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76893-45:
(7*7)+(6*6)+(5*8)+(4*9)+(3*3)+(2*4)+(1*5)=183
183 % 10 = 3
So 76893-45-3 is a valid CAS Registry Number.

Kinetics of the reaction of 2-chloro-3-nitro- and 2-chloro-5-nitropyridines with aryloxide ions in methanol
El-Bardan, Ali A.
, p. 347 - 353 (2007/10/03)
The kinetics of the reaction of 2-chloro-3-nitropyridine (ortho-like) and 2-chloro-5-nitropyridine (para-like) with a series of aryloxide ions were studied in methanol at different temperatures. Plots of ΔH* versus ΔS* for both reactions gave good straight lines with isokinetic temperatures of 168 and 195°C. Good linear relationships were obtained from the plots of log k2 against σ° values with relatively large negative ρ values indicating the formation of Meisenheimer σ-complex intermediates. Plots of log k2 against pKa values gave good straight lines indicating that the reactions show an appreciable degree of bond formation in the transition state. An addition-elimination mechanism is suggested. Copyright
