Check Digit Verification of cas no

The CAS Registry Mumber 203806-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,8,0 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 203806-77:
(8*2)+(7*0)+(6*3)+(5*8)+(4*0)+(3*6)+(2*7)+(1*7)=113
113 % 10 = 3
So 203806-77-3 is a valid CAS Registry Number.

Application of the asymmetric aminohydroxylation reaction for the syntheses of HIV-protease inhibitor, hydroxyethylene dipeptide isostere and γ-amino acid derivative

Kondekar, Nagendra B.,Kandula, Subba Rao V.,Kumar, Pradeep

, p. 5477 - 5479 (2007/10/03)

An enantioselective synthesis of lactone 1, a precursor to the (2R,4S,5S) hydroxyethylene dipeptide isostere and amino acid AHPPA 2 has been accomplished from the common intermediate 5 employing Sharpless asymmetric aminohydroxylation as the key step.

Development of selective tight-binding inhibitors of leukotriene A4 hydrolase

Yuan,Munoz,Wong,Haeggstrom,Wetterholm,Samuelsson

, p. 211 - 220 (2007/10/02)

Leukotriene A4 hydrolase is a zinc-containing enzyme which exhibits both epoxide hydrolase and aminopeptidase activities. Since the enzyme product leukotriene B4 is an inflammatory mediator, it is of interest to develop selective inh
