41274-76-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 41274-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,2,7 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 41274-76:
(7*4)+(6*1)+(5*2)+(4*7)+(3*4)+(2*7)+(1*6)=104
104 % 10 = 4
So 41274-76-4 is a valid CAS Registry Number.

Electrophilicity parameters for benzylidenemalononitriles

Lemek, Tadeusz,Mayr, Herbert

, p. 6880 - 6886 (2003)

Kinetics of the reactions of stabilized carbanions (derived from nitroethane, diethyl malonate, ethyl cyanoacetate, ethyl acetoacetate, acetyl acetone) with benzylidenemalononitriles have been determined in dimethyl sulfoxide solution at 20 °C. The second-order rate constants are employed to determine the electrophilicity parameters E of the benzylidenemalononitriles according to the correlation equation log k (20 °C) = s(E + N). Comparison with literature data shows that this equation allows the semiquantitative prediction of the reactivities of benzylidenemalononitriles toward a wide variety of nucleophiles, including carbanions, enamines, amines, water, and hydroxide.
