135103-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135103-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,1,0 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135103-80:
(8*1)+(7*3)+(6*5)+(5*1)+(4*0)+(3*3)+(2*8)+(1*0)=89
89 % 10 = 9
So 135103-80-9 is a valid CAS Registry Number.

Stereoselective synthesis of hydroxyethylene dipeptide isostere from sugar
Chakraborty,Gangakhedkar
, p. 2045 - 2056 (2007/10/03)
Regioselective opening of the aziridine ring in the carbohydrate-based precursor led to the stereoselective synthesis of N-Boc-O-benzyl-(4S,5S)-5-amino-4-hydroxy-6-phenylhexanoic acid methyl ester, the hydroxyethylene dipeptide isostere moiety of potent HIV-1 protease inhibitor.
