Check Digit Verification of cas no

The CAS Registry Mumber 60041-92-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,0,4 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 60041-92:
(7*6)+(6*0)+(5*0)+(4*4)+(3*1)+(2*9)+(1*2)=81
81 % 10 = 1
So 60041-92-1 is a valid CAS Registry Number.

An advantageous synthesis of new indazolone and pyrazolone derivatives

Correa, Arkaitz,Tellitu, Imanol,Domínguez, Esther,SanMartin, Raul

, p. 11100 - 11105 (2007/10/03)

The synthesis of new indazolone and pyrazolone derivatives starting from methyl anthranilate type substrates is presented. This general approach constitutes a novel and advantageous alternative for the synthesis of the target heterocycles, which implies the use of the environmentally friendly oxidizer PIFA. The synthetic design includes the oxidation of N-arylamides by the hypervalent iodine reagent to the corresponding N-acylnitrenium ions, which can be intramolecularly trapped by an amine moiety to furnish the title compounds by formation of a new N-N single bond.
