Calculate Digit Verification of CAS Registry Number 889893-47:
(8*8)+(7*8)+(6*9)+(5*8)+(4*9)+(3*3)+(2*4)+(1*7)=274
274 % 10 = 4
So 889893-47-4 is a valid CAS Registry Number.

, p. 4103 - 4109 (2006)

(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
