20898-09-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20898-09-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,9 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20898-09:
(7*2)+(6*0)+(5*8)+(4*9)+(3*8)+(2*0)+(1*9)=123
123 % 10 = 3
So 20898-09-3 is a valid CAS Registry Number.

Aza vinyl sulfones: Synthesis and evaluation as antiplasmodial agents

Glória, Paulo M.C.,Gut, Jiri,Gonalves, Lídia M.,Rosenthal, Philip J.,Moreira, Rui,Santos, Maria M.M.

scheme or table, p. 7635 - 7642 (2012/01/05)

A series of novel aza vinyl sulfones were designed, synthesized in good yields and evaluated as antiplasmodial agents. Tested compounds did not show activity against papain or the Plasmodium falciparum cysteine protease falcipain-2. However, a number of t

Synthesis of PHI (Peptide Histidine Isoleucine) and Related Peptides and Immunochemical Confirmation of Amino Acid Residue in Position 24 of PHI with use of the Synthetic Peptides

Nokihara, K.,Yanaihara, C.,Iguchi, K.,Fukata, S.,Tanaka, M.,et al.

, p. 7909 - 7916 (2007/10/02)

An immunochemical approach, using synthetic peptides, was employed to establish the nature of residue 24 in the amino acid sequence of PHI (peptide histidine isoleucine).PHI(20-27) and 24>-PHI(20-27) were synthesized by conventional solutio
