349434-46-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 349434-46-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,9,4,3 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 349434-46:
(8*3)+(7*4)+(6*9)+(5*4)+(4*3)+(3*4)+(2*4)+(1*6)=164
164 % 10 = 4
So 349434-46-4 is a valid CAS Registry Number.

Conformations, equilibrium thermodynamics and rotational barriers of secondary thiobenzanilides

Kozic, Ján,Novák, Zdeněk,?ímal, Václav,Profant, Václav,Kune?, Ji?í,Vin?ová, Jarmila

, p. 2072 - 2083 (2016/04/09)

The article deals with conformational behaviour of 2-methoxy-2′-hydroxythiobenzanilides. The CS-NH group of these compounds preferentially adopts the Z-conformation. Entropy favours the Z-conformer over the E-conformer, whereas enthalpy slightly favours the E-conformer over the Z-conformer. The rotational barrier about the CS-NH bond was determined to be (81.5±0.4) kJ/mol. No significant rotational barrier was found on the Ar-CS and Ar-NH bonds. All experimental outcomes are compared with the results of quantum-chemical calculations.
