Calculate Digit Verification of CAS Registry Number 889893-50:
(8*8)+(7*8)+(6*9)+(5*8)+(4*9)+(3*3)+(2*5)+(1*0)=269
269 % 10 = 9
So 889893-50-9 is a valid CAS Registry Number.

, p. 4103 - 4109 (2007/10/03)

(R)-4-Hydroxymethyl-2-phenyl-4,5-dihydrooxazol-4-ylmethyl acetate was efficiently obtained by lipase-catalyzed asymmetrization of the prochiral diol. (R)-4-Hydroxymethyl-2-phenyl-4,5-dihydrooxazol-4-ylmethyl acetate was converted to (R)-2-(hydroxymethyl)g
