Check Digit Verification of cas no

The CAS Registry Mumber 20797-48-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,9 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20797-48:
(7*2)+(6*0)+(5*7)+(4*9)+(3*7)+(2*4)+(1*8)=122
122 % 10 = 2
So 20797-48-2 is a valid CAS Registry Number.

Synthesis and characterization of two novel biological-based nano organo solid acids with urea moiety and their catalytic applications in the synthesis of 4,4′-(arylmethylene)bis(1H-pyrazol-5-ol), coumarin-3-carboxylic acid and cinnamic acid derivatives under mild and green conditions

Zolfigol, Mohammad Ali,Ayazi-Nasrabadi, Roya,Baghery, Saeed

, p. 71942 - 71954 (2015/09/08)

2-Carbamoylhydrazine-1-sulfonic acid and carbamoylsulfamic acid as novel, mild and biological-based nano organocatalysts with urea moiety were designed, synthesized and fully characterized by FT-IR, 1H NMR, 13C NMR, mass spectrometry, elemental analysis, thermal gravimetric, derivative thermal gravimetric, X-ray diffraction patterns, scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, atomic force microscopy and UV/Vis analysis. The catalytic applications of 2-carbamoylhydrazine-1-sulfonic acid and carbamoylsulfamic acid were studied in the synthesis of 4,4′-(arylmethylene)bis(1H-pyrazol-5-ol), coumarin-3-carboxylic acid and cinnamic acid derivatives via the condensation reaction between several aromatic aldehydes and 1-phenyl-3-methylpyrazol-5-one (synthesis of 4,4′-(arylmethylene)bis(1H-pyrazol-5-ols)), the Knoevenagel condensation of Meldrum's acid with salicylaldehyde derivatives (synthesis of coumarin-3-carboxylic acids) and the condensation of Meldrum's acid with aromatic aldehydes (synthesis of cinnamic acids) under mild and solvent-free conditions. In the presented studies, some products were formed and reported for the first time. The described nano organo solid acids have potential in industry.
