Check Digit Verification of cas no
The CAS Registry Mumber 126917-44-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,9,1 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 126917-44:
(8*1)+(7*2)+(6*6)+(5*9)+(4*1)+(3*7)+(2*4)+(1*4)=140
140 % 10 = 0
So 126917-44-0 is a valid CAS Registry Number.

Concise Synthesis of Optically Active Oxirane Precursors for the Preparation of Triazole Antifungals Using the Friedel-Crafts Reaction of (S)-2-Tosyloxypropionyl Chloride

Optically active epoxide (2R,3S)-4, a key intermediate for the preparation of triazole antifungal agents (4R,5R)-1 and (2R,3R)-2 (X = 2,4-F2), was synthesized.The Friedel-Crafts reaction between the (S)-lactic acid derivative (S)-10 and m-difluorobenzene gave the (R)-2-chloropropiophenone derivative (R)-11, which was converted into (2R,3R)-18 via Peterson olefination, stereoselective osmium(VIII) oxide oxidation, and mesylation.Treatment of (2R,3R)-18 with sodium triazolide gave (2R,3S)-4.Similarly, the 4-chlorophenyl analog (2R,3S)-4' was prepared.
