188184-66-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188184-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,1,8 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 188184-66:
(8*1)+(7*8)+(6*8)+(5*1)+(4*8)+(3*4)+(2*6)+(1*6)=179
179 % 10 = 9
So 188184-66-9 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
