199926-83-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 199926-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,9,2 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 199926-83:
(8*1)+(7*9)+(6*9)+(5*9)+(4*2)+(3*6)+(2*8)+(1*3)=215
215 % 10 = 5
So 199926-83-5 is a valid CAS Registry Number.

Synthesis and reaction of chiral 4,5-disubstituted 2-oxazolidinones from 3-ethoxy-6-(N-alkyl-N-tert-butoxy- carbonyl)aminohexa-2,4-dienoates in the presence of concentrated sulfuric acid supported on silica gel

Kawano, Tomikazu,Negoro, Kenji,Nitta, Hajime,Ueda, Ikuo

, p. 1261 - 1278 (2007/10/03)

Reaction of chiral 3-ethoxy-6-(N-alkyl-N-tert-butoxycarbonyl)amino-hexa- 2,4-dienoates (3) and related compounds with 97% concentrated sulfuric acid supported on silica gel proceeded stereo- and regio-selectively to yield chiral 4,5-disubstituted N-alkyl-2-oxazolidinones (7). Under the limited conditions, 7 were converted into N-alkyl-2-pyrrolylacetates (8) and 2- oxazolidinone derivatives (12) which may serve as a chiral auxiliary.
