869012-73-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 869012-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,0,1 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 869012-73:
(8*8)+(7*6)+(6*9)+(5*0)+(4*1)+(3*2)+(2*7)+(1*3)=187
187 % 10 = 7
So 869012-73-7 is a valid CAS Registry Number.

Enantiodivergent, biocatalytic routes to both taxol side chain antipodes
Feske, Brent D.,Kaluzna, Iwona A.,Stewart, Jon D.
, p. 9654 - 9657 (2007/10/03)
Two enantiocomplementary bakers' yeast enzymes reduced an α-chloro-β-keto ester to yield precursors for both enantiomers of the N-benzoyl phenylisoserine Taxol side chain. After base-mediated ring closure of the chlorohydrin enantiomers, the epoxides were
