81153-44-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81153-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,5 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81153-44:
(7*8)+(6*1)+(5*1)+(4*5)+(3*3)+(2*4)+(1*4)=108
108 % 10 = 8
So 81153-44-8 is a valid CAS Registry Number.

Synthesis and characterization of new 1H-pyrazolo[3,4-b]pyridine phosphoramidate derivatives

Pedrosa, Leandro F.,De Macedo, William P.,Furtado, Antonia C.R.,Guedes, Guilherme P.,Borges, Julio C.,Resende, Jackson A.L.C.,Vaz, Maria G.F.,Bernardino, Alice M.R.,De Souza, Marcos C.

, p. 38 - 50 (2014)

Twelve new 1H-pyrazolo[3,4-b]pyridine phosphoramidate derivatives were synthesized under mild conditions by nucleophilic aromatic substitution reaction of aminoalkylphosphoramidates over 4-Cl substituted pyrazolo[3,4-b]pyridine in good yields. The new com

Mass spectrometry of pyrazolo[3,4-b]pyrido[2′,3′-b]-1,6-naphthyridines and dipyrazolo[3,4-b];3′,4′-h]-1,6-naphthyridines

Khakwani, Samia,Aslam, Samina,Mussadiq, Sara,Shahi, Mehrzadi Noureen,Perveen, Najma,Rolim Bernardino, Alice M.,Khan, Misbahul Ain

, p. 2601 - 2604 (2016/10/17)

The mass spectra of several pyrazolo[3,4-b]pyrido[2′,3′-b]-1,6-naphthyridines and dipyrazolo[3,4-b];3′,4′-h]-1,6-naphthyridines are presented. The fragmentation is initiated by the elimination of CO molecule [m/z 28] followed by other fragments, such as h

The identification a novel, selective, non-steroidal, functional glucocorticoid receptor antagonist

scheme or table, p. 2340 - 2343 (2010/08/22)

The identification of novel, potent, non-steroidal/small molecule functional GR antagonist GSK1564023A selective over PR is described. Associated structure-activity relationships and the process of optimisation of an initial HTS hit are also described.
