129111-74-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129111-74-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,1 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129111-74:
(8*1)+(7*2)+(6*9)+(5*1)+(4*1)+(3*1)+(2*7)+(1*4)=106
106 % 10 = 6
So 129111-74-6 is a valid CAS Registry Number.

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.
