159489-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159489-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,4,8 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 159489-45:
(8*1)+(7*5)+(6*9)+(5*4)+(4*8)+(3*9)+(2*4)+(1*5)=189
189 % 10 = 9
So 159489-45-9 is a valid CAS Registry Number.

The revised structure of the antibiotic Tue 1718 B confirmed by synthesis
Postels, Hans-Thomas,Koenig, Wilfried A.
, p. 4535 - 4538 (2007/10/02)
The revised structure of the dipeptide antibiotic Tue 1718 B was confirmed by synthesis of two possible diastereoisomers of L-valyl-dihydroxylysine 2. Comparison of the NMR spectra of the synthetic and natural products indicates (2S,3S,5S)- or (2S,3R,5S)-
