Check Digit Verification of cas no
The CAS Registry Mumber 18928-01-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,2 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18928-01:
(7*1)+(6*8)+(5*9)+(4*2)+(3*8)+(2*0)+(1*1)=133
133 % 10 = 3

An alternative synthesis of N5-Acetyl-N5-hydroxy-L-ornithine from L-Ornithine
Milewska,Chimiak
, p. 233 - 234 (2007/10/02)
N5-Acetyl-N5-hydroxy-L-ornithine is obtained from L-ornithine in 20% overall yield via oxidation of the ω-amino group in N2-benzyloxycarbonyl-L-ornithine tert-butyl ester with dibenzoyl peroxide and subsequent N5-acetylation.
