123685-57-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 123685-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,6,8 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123685-57:
(8*1)+(7*2)+(6*3)+(5*6)+(4*8)+(3*5)+(2*5)+(1*7)=134
134 % 10 = 4
So 123685-57-4 is a valid CAS Registry Number.

6-Substituted 2,4-diamino-5-methylpyrido[2,3-d]pyrimidines as inhibitors of dihydrofolate reductases from Pneumocystis carinii and Toxoplasma gondii and as antitumor agents

Gangjee,Vasudevan,Queener,Kisliuk

, p. 1778 - 1785 (1995)

The synthesis and biological activity of 15 6-substituted 2,4-diamino-5- methylpyrido[2,3-d]-pyrimidines are reported. These compounds were synthesized in improved yields by modifications of procedures previously reported by us. Specifically, dimethoxyphe

Synthesis and evaluation of novel fluorinated pyrazolo-1,2,3-triazole hybrids as antimycobacterial agents

Emmadi, Narender Reddy,Bingi, Chiranjeevi,Kotapalli, Sudha Sravanti,Ummanni, Ramesh,Nanubolu, Jagadeesh Babu,Atmakur, Krishnaiah

supporting information, p. 2918 - 2922 (2015/06/22)

A library of novel 3-trifluoromethyl pyrazolo-1,2,3-triazole hybrids (5-7) were accomplished starting from 5-phenyl-3-(trifluoromethyl)-1H-pyrazol-4-amine (1) via key intermediate 2-azido-N-(5-phenyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)acetamide (3) throu

Potent inhibition of thymidylate synthase by two series of nonclassical quinazolines

McNamara,Berman,Fry,Werbel

, p. 2045 - 2051 (2007/10/02)

The synthesis and biological activity of two series of nonclassical thymidylate synthase (TS) inhibitors are described. The first is a series of 10-propargyl-5.8-dideazafolic acid derivatives (10a-j) and the second is a series of the analogous 2-desamino
