187868-53-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 187868-53-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,8,6 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 187868-53:
(8*1)+(7*8)+(6*7)+(5*8)+(4*6)+(3*8)+(2*5)+(1*3)=207
207 % 10 = 7
So 187868-53-7 is a valid CAS Registry Number.

Stereoselective synthesis of dehydroamino acids using malonic acid half oxyester and aromatic aldehydes

Singjunla, Yuttapong,Colombano, Silvia,Baudoux, Jér?me,Rouden, Jacques

, p. 2369 - 2375 (2016/04/26)

An efficient and direct approach was developed for the synthesis of α,β-dehydroamino acid derivatives with a broad range of substrates. Amido-substituted Malonic Acid Half Oxyesters (MAHOs) have proven to be excellent partners of various aromatic aldehyde

MACROCYCLIC HEPATITIS C PROTEASE INHIBITORS

-

Page/Page column 47, (2008/12/07)

The present invention provides novel macrocyclic compounds that mimic peptide substrates of the hepatitis C viral protease and inhibit the viral protease, more particularly as inhibitors of the NS3 serine protease from hepatitis C virus. Methods for synthesis of the compounds are also provided. The compounds find utility as antiviral agents directed at hepatitis C. The invention further provides methods of employing such inhibitors, alone or in combination with other therapeutic agents, to treat hepatitis C infection in a subject in need of such treatment.
