Check Digit Verification of cas no

The CAS Registry Mumber 17099-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,0,9 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 17099-20:
(7*1)+(6*7)+(5*0)+(4*9)+(3*9)+(2*2)+(1*0)=116
116 % 10 = 6
So 17099-20-6 is a valid CAS Registry Number.

Heterogeneous Catalysis with Basic Compounds to Achieve the Synthesis and C-N Cleavage of Azetidin-2-ones under Microwave Irradiation

Alcaraz, Yolanda,Cruz, Francisco,De La Cruz, Fabiola N.,Delgado, Francisco,Domínguez, José Manuel,Galván, Adriana,Gomez, Clarisa Villegas,Martínez, Merced,Vázquez, Miguel A.

, p. 3625 - 3637 (2019)

The synthesis of azetidin-2-ones with a completely heterogeneous catalysis is reported. The use of basic compounds as solid catalysts allowed for the synthesis of azetidin-2-ones under microwave irradiation without organic additives such as triethylamine. An excellent catalyst for this transformation was Mg-Al hydroxide (MAH). The present methodology offers the advantages of non-hazardous reaction conditions, short reaction times, high yields, and catalyst reusability. Different substitution groups were tested on the imines and acyl chlorides to explore the scope of the reaction. Unconventional N-C4 bond cleavage was detected in azetidin-2-ones. MAH was characterized by N 2 adsorption-desorption, X-ray diffraction (XRD), scanning electron microscopy (SEM), and high-resolution transmission electron microscopy (HR-TEM).

Polarographic investigations on azomethines: Benzal-p-chloranilines in alkaline medium and effect of substituents on half-wave potentials

Katiyar, Sarvagya S.,Lalithambika, M.

, p. 961 - 973 (2007/10/02)

Polarographic behavior of twenty-four substituted benzal-p-chloranilines has been investigated in 50percent methanol-water medium in alkaline pH range.The experimental conditions for the study were so designed that no appreciable hydrolysis of the Schiff
