50366-20-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 50366-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,3,6 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 50366-20:
(7*5)+(6*0)+(5*3)+(4*6)+(3*6)+(2*2)+(1*0)=96
96 % 10 = 6
So 50366-20-6 is a valid CAS Registry Number.

Tetrabromomethane as an Organic Catalyst: a Kinetic Study of CBr4-Catalyzed Schiff Condensation

Bolotin, Dmitrii S.,Kukushkin, Vadim Yu.,Tolstoy, Peter M.,Vovk, Mikhail A.,Yunusova, Sevilya N.

supporting information, p. 6763 - 6769 (2020/10/27)

Tetrabromomethane functions as an organic catalyst for non-redox reactions of carbonyl species and, in particular, it enhances the aldehyde–acyl hydrazide condensation to give N-acyl hydrazones. This simple, inexpensive, and commercially available halomet

Efficient synthesis of functionalized 1,3-dihydroisobenzofurans from salicylaldehydes: Application to the synthesis of escitalopram

Wang, Peng,Zhang, Rui,Cai, Jin,Chen, Jun-Qing,Ji, Min

, p. 549 - 552 (2014/05/06)

An efficient synthesis of substituted 1,3-dihydroisobenzofurans is developed. In this novel route, o-aroylbenzaldehydes, as key intermediates, can be obtained by lead tetraacetate oxidation of N-aroylhydrazones of salicylaldehydes. The mild and general st

Synthesis of some novel pharmacologically active schiff bases using microwave method and their derivatives formazans by conventional method

Desai, Krunal G.,Desai

, p. 2097 - 2101 (2007/10/03)

Condensation of p-nitrobenzoylhydrazide 1 with substituted aromatic aldehydes 2 under microwave irradiation and by conventional method provide Schiff bases 3a-j. Schiff bases 3a-j on condensation with diazonium salt of 6-methoxy-2-aminobenzothiazole give formazans 4a-j. This reaction is carried out only by conventional method.
