Check Digit Verification of cas no

The CAS Registry Mumber 33650-07-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,5 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 33650-07:
(7*3)+(6*3)+(5*6)+(4*5)+(3*0)+(2*0)+(1*7)=96
96 % 10 = 6
So 33650-07-6 is a valid CAS Registry Number.

Kinetics of Phase-Transfer Formation of Potassium Carbazolate, Catalyzed with 18-Crown-6

Frolova,Kachurin

, p. 74 - 76 (2001)

Kinetics of formation of potassium carbazolate in the system liquid-solid, catalyzed with 18-crown-6, was studied. Applicability of the previously proposed macrokinetic model to this process was demonstrated.

Regioselective ring-opening of epoxides by carbazole: A direct preparation of novel N-(β-hydroxyalkyl)carbazoles

Soltani Rad, Mohammad Navid,Behrouz, Somayeh,Ahrari, Samira

, p. 137 - 140 (2016/04/20)

The influence of various parameters including solvent, base and temperature on the reaction between carbazole and epoxides was studied This led to the development of a regioselective ring-opening of epoxides by the potassium salt of carbazole in DMSO at 100 °C which is a straightforward way to prepare new N-(β-hydroxyalkyl)carbazoles in good to excellent yields. Fifteen new compounds are described.
