21112-02-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21112-02-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,1 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21112-02:
(7*2)+(6*1)+(5*1)+(4*1)+(3*2)+(2*0)+(1*2)=37
37 % 10 = 7
So 21112-02-7 is a valid CAS Registry Number.

Solvent Dependence of the Ionization of Nitrophenylmethanes

Fogel, Paula,Farrel, Patrick G.,Lelievre, Jacques,Chatrousse, Alain P.,Terrier, Francois

, p. 711 - 716 (2007/10/02)

The solvent dependence of proton abstraction from various nitrophenylmethanes has been examined for aqueous dimethyl sulphoxide and methanolic dimethyl sulphoxide solutions.Even though the compounds studied vary considerably in thermodynamic acidity (pKa), their proton-abstraction rates all show the same solvent dependence.It is suggested that the transition states for these reactions all occur at similar positions on the reaction pathway, and that transition state imbalances exist for these proton transfers.
