850494-64-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 850494-64-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,4,9 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 850494-64:
(8*8)+(7*5)+(6*0)+(5*4)+(4*9)+(3*4)+(2*6)+(1*4)=183
183 % 10 = 3
So 850494-64-3 is a valid CAS Registry Number.

, p. 289 - 297 (2007/10/03)
An enantioselective synthesis of N-Boc-(2S,3S)-3-hydroxy glutamic acid dimethyl ester (92% ee) is described. Starting from enantiomerically enriched (93% ee) (2S,3S)-2,3-epoxy-5-hexen-1-ol, easily available by Sharpless asymmetric epoxidation, the protect
