Check Digit Verification of cas no

The CAS Registry Mumber 138110-76-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,1,1 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138110-76:
(8*1)+(7*3)+(6*8)+(5*1)+(4*1)+(3*0)+(2*7)+(1*6)=106
106 % 10 = 6
So 138110-76-6 is a valid CAS Registry Number.

One-pot sequential asymmetric hydrogenation of β-aryl-β-aryloxy acroleins

Liu, Yufeng,Chen, Jianzhong,Zhang, Zhenfeng,Qin, Jian,Zhao, Min,Zhang, Wanbin

, p. 7099 - 7102 (2016/07/30)

A one-pot sequential asymmetric hydrogenation of β-aryl-β-aryloxy acroleins has been realized for the preparation of chiral 3-aryl-3-aryloxy alcohols with excellent yields and good enantioselectivities. This methodology can be employed in new synthetic routes for the synthesis of fluoxetine, atomoxetine, and related analogues.

An efficient chemoenzymatic route to the antidepressants (R)-fluoxetine and (R)-tomoxetine

Bracher, Franz,Litz, Thomas

, p. 877 - 880 (2007/10/03)

(S)-1-Phenyl-3-buten-1-ol (1), prepared in high optical purity by enzymatic resolution of the racemate, is a convenient building block for the synthesis of (R)-fluoxetine (7a) and (R)-tomoxetine (7b). Compound 1 was converted to the title drugs by etherification with appropriate phenols under Mitsunobu conditions, ozonolysis of the terminal double bond, mesylation of the resulting alcohol and substitution with methylamine.

Chemoenzymatic Synthesis of Both Enantiomers of Fluoxetine

Chenevert, Robert,Fortier, Genevieve

, p. 1603 - 1606 (2007/10/02)

Both enantiomers of fluoxetine have been synthesized from ethyl benzoylacetate.The key step is the enantioselective reduction of the starting material by baker's yeast.
