Check Digit Verification of cas no
The CAS Registry Mumber 204587-95-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,5,8 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 204587-95:
(8*2)+(7*0)+(6*4)+(5*5)+(4*8)+(3*7)+(2*9)+(1*5)=141
141 % 10 = 1
So 204587-95-1 is a valid CAS Registry Number.

An expeditious asymmetric synthesis of allophenylnorstatine
Bunnage, Mark E.,Davies, Stephen G.,Goodwin, Christopher J.,Ichihara, Osamu
, p. 3975 - 3986 (2007/10/02)
Allophenylnorstatine [APNS; (2S,3S)-3-amino-2-hydroxy-4-phenylbutanoic acid], a novel amino acid found in the kynostatin class of HIV-I protease inhibitors, has been prepared in 39% overall yield via a tandem conjugate addition-electrophilic hydroxylation protocol using lithium (S)-(α-methylbenzyl)benzylamide and (+)-(camphorsulfonyl)oxaziridine. An unprecedented level of molecular recognition between a homochiral β-amino enolate and a homochiral oxaziridine is identified and the importance of enolate geometry upon hydroxylation stereoselectivity is also addressed.
