Check Digit Verification of cas no

The CAS Registry Mumber 201798-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,7,9 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 201798-53:
(8*2)+(7*0)+(6*1)+(5*7)+(4*9)+(3*8)+(2*5)+(1*3)=130
130 % 10 = 0
So 201798-53-0 is a valid CAS Registry Number.

Enantiospecific and diastereoselective synthesis of syn-β-amino-α-hydroxy acids

Sugimura, Hideyuki,Miura, Masayuki,Yamada, Nobuko

, p. 4089 - 4099 (2007/10/03)

The reaction of chiral α-hydroxy β,γ-unsaturated esters with tosyl isocyanate followed by cyclization of the resulting allylic carbamates with iodine in the presence of sodium carbonate provided trans-4,5-disubstituted 2-oxazolidinone derivatives in a highly diastereoselective manner. The subsequent removal of the iodo group and the protective functionality afforded the syn-β-amino-α-hydroxy acids. Using the reaction sequence, (2R,3S)- and (2S,3R)-3-amino-2-hydroxy acids were synthesized with high enantioselectivity.
