Check Digit Verification of cas no

The CAS Registry Mumber 207449-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,4,4 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 207449-90:
(8*2)+(7*0)+(6*7)+(5*4)+(4*4)+(3*9)+(2*9)+(1*0)=139
139 % 10 = 9
So 207449-90-9 is a valid CAS Registry Number.

Kinetics and Mechanism of the Alkaline Hydrolysis of 2,4-Dinitrophenyl 4′-Hydroxyphenylpropiolate

Cevasco, Giorgio,Pardini, Roberto,Thea, Sergio

, p. 665 - 669 (2007/10/03)

The alkaline hydrolysis of the title ester was studied in 40 % dioxane/water (v/v) solutions. Kinetic data, reactivity comparisons with model substrates and activation parameters appear to suggest the occurrence of a dissociative E1cB pathway although participation of the associative mechanism cannot be definitely ruled out.
