131490-83-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131490-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,9 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131490-83:
(8*1)+(7*3)+(6*1)+(5*4)+(4*9)+(3*0)+(2*8)+(1*3)=110
110 % 10 = 0
So 131490-83-0 is a valid CAS Registry Number.

A chemo-enzymatic synthesis of the N-terminal aminoacid lactone of Nikkomycin B
Kapeller,Jary,Hayden,Griengl
, p. 245 - 251 (2007/10/03)
(2S,3S,4S)-4-(4-Acetoxyphenyl)-2-amino-3-methylbutan-4-olide (S,S,S)-11, a precursor for the aminoacid part of Nikkomycin B, was prepared in a five step synthesis in 12% yield, involving two enzymatic steps. First enantiopurity was achieved by resolution
