163685-22-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163685-22-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,6,8 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 163685-22:
(8*1)+(7*6)+(6*3)+(5*6)+(4*8)+(3*5)+(2*2)+(1*2)=151
151 % 10 = 1
So 163685-22-1 is a valid CAS Registry Number.

Atfani, Mohamed,Lubell, William D.
, p. 3184 - 3188 (1995)
An efficient method for synthesizing enantiopure isoxazole amino acids has been developed. (2S)-2-Amino-3-(3-tert-butyl-5-oxo-2H-isoxazol-4-yl)propionic acid (1) was synthesized in three steps from L-γ-methyl N-(9-(9-phenylfluorenyl)glutamate (2) in 46per
