Check Digit Verification of cas no

The CAS Registry Mumber 21741-98-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,4 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21741-98:
(7*2)+(6*1)+(5*7)+(4*4)+(3*1)+(2*9)+(1*8)=100
100 % 10 = 0
So 21741-98-0 is a valid CAS Registry Number.

N -Oxide-Controlled Chemoselective Reduction of Nitrofuroxans

Fershtat, Leonid L.,Bystrov, Dmitry M.,Zhilin, Egor S.,Makhova, Nina N.

, p. 747 - 756 (2019/01/23)

A facile and chemoselective SnCl 2 -mediated mild reduction of regioisomeric 3- and 4-nitrofuroxans for the synthesis of aminofurazans and aminofuroxans in good yields is developed. Reduction of 4-nitrofuroxans results in the selective formation of 4-aminofuroxans, while analogous reduction of 3-nitrofuroxans affords 3-aminofurazans as a result of simultaneous reduction of the nitro group and exocyclic N-O bond.

Synthesis of new dithiolethione and methanethiosulfonate systems endowed with pharmaceutical interest

Gabriele, Elena,Porta, Federica,Facchetti, Giorgio,Galli, Corinna,Gelain, Arianna,Meneghetti, Fiorella,Rimoldi, Isabella,Romeo, Sergio,Villa, Stefania,Ricci, Chiara,Ferri, Nicola,Asai, Akira,Barlocco, Daniela,Sparatore, Anna

, p. 235 - 250 (2017/03/09)

Here we report synthetic methodology affording in the most efficient way the rapid preparation of new dithiolethiones (DTTs) and methanethiosulfonates (MTSs). These were evaluated as STAT3 inhibitors since these electrophilic systems could react with thio

One-pot synthesis of 3-amino-4-aryl- and 3-amino-4-hetarylfurazans

Sheremetev

, p. 1057 - 1059 (2007/10/03)

A "one pot" method for the synthesis of 3-amino-4-aryl- and 3-amino-4-hetarylfurazans from β-aryl- and 4-β-hetaryl-β-oxo acid esters was developed.
