Check Digit Verification of cas no
The CAS Registry Mumber 247178-57-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,1,7 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 247178-57:
(8*2)+(7*4)+(6*7)+(5*1)+(4*7)+(3*8)+(2*5)+(1*7)=160
160 % 10 = 0
So 247178-57-0 is a valid CAS Registry Number.

Novel synthesis of (-)-bestatin from L-aspartic acid
Seki, Masahiko,Nakao, Kazuya
, p. 1304 - 1307 (1999)
Oxazoline-4-acetate derivative 3 that could be readily obtained from L-aspartic acid was subjected to highly stereoselective hydroxylation, and subsequent Mitsunobu inversion of the hydroxyl group led to (2S,3R)-3-amino-3-benzyl-2-hydroxybutanoic acid der
