Check Digit Verification of cas no

The CAS Registry Mumber 126440-72-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,4,4 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 126440-72:
(8*1)+(7*2)+(6*6)+(5*4)+(4*4)+(3*0)+(2*7)+(1*2)=110
110 % 10 = 0
So 126440-72-0 is a valid CAS Registry Number.

Synthesis and biological activity studies of novel arylazo pyrazoles

Revanasiddappa,Jose, Neethu

, p. 27 - 30 (2019/01/21)

A novel series of 3,5-dimethyl-arylazopyrazoles (4a-j) was synthesized by the condensation of hydrazono derivatives (2a-j) (obtained by the reaction of 1,3-diketone with diazonium salts in the presence of sodium acetate) with 2-hydroxy benzohydrazide (3)

Synthesis, characterization and antibacterial screening of new pyrazole and pyrazoline-5-one derivatives

Nagaraju,Srinivasulu,Doraswamy,Venkata Ramana

, p. 293 - 298 (2012/03/11)

A series of N′-(p-toluene sulphonyl)-3-methyl-4-(substituted arylhydrazono)-2-pyrazoline-5-ones and N′-(2-hydroxybenzoyl)-3,5-dimethyl- 4-(substituted arylazo)pyrazoles have been synthesized and characterized by chemical analysis, IR and 1H NMR spectral data. The compounds have been screened for antibacterial activity against Staphylococcus aureus and Escherichia coli.
