Check Digit Verification of cas no

The CAS Registry Mumber 180713-67-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,7,1 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 180713-67:
(8*1)+(7*8)+(6*0)+(5*7)+(4*1)+(3*3)+(2*6)+(1*7)=131
131 % 10 = 1
So 180713-67-1 is a valid CAS Registry Number.

A series of stereochemically defined cyclic ethers as P2-ligands were incorporated in an allophenylnorstatine-based isostere to provide a new series of HIV-1 protease inhibitors. Inhibitors 3b and 3c, containing conformationally constrained cyclic ethers,

Process for the preparation of (2r,3s)-3-amino-1,2-oxirane

-

, (2008/06/13)

A process for producing (2R,3S)-3-amino-4-phenylbutane-1,2-epoxide compounds which comprises treating a (2S,3S)-3-amino-1-halo-2-hydroxy-4-phenylbutane compound or a (2S,3S)-3-amino-4-phenylbutane-1,2-epoxide with a carboxylic acid quaternary ammonium salt or a carboxylic acid metal salt a quaternary ammonium salt and a quaternary ammonium salt, to give a (2S,3S)-1-acyloxy-3-amino-2-hydroxy-4-phenylbutane compound, further treating the same with a sulfonic acid halide in the presence of an organic base to give a (2S,3S)-1-acyloxy-3-amino-2-sulfonyloxy-4-phenylbutane compound, furthermore treating said compound with an inorganic base.
