180597-97-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 180597-97-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,5,9 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 180597-97:
(8*1)+(7*8)+(6*0)+(5*5)+(4*9)+(3*7)+(2*9)+(1*7)=171
171 % 10 = 1
So 180597-97-1 is a valid CAS Registry Number.

An anomalous Dakin-West reaction of N-carbamate substituted prolines and trifluoroacetic anhydride

Kawase, Masami,Hirabayashi, Michitaka,Koiwai, Hiromi,Yamamoto, Katsumi,Miyamae, Hiroshi

, p. 641 - 642 (1998)

A novel transformation of N-alkoxycarbonylprolines 1 to 4-trifluoroacetyl-2,3-dihydropyrroles 2 was efficiently realized by utilizing trifluoroacetic anhydride, in which probable intermediates were mesoionic 1,3-oxazolium-5-olates B.

ENANTIOMERIC QUANTIFICATIONS OF AMINO ACIDS THROUGH THEIR Nα-ACYL AMIDES BY GAS CHROMATOGRAPHY.

Hosten, N.,Antenuis, M.J.O

, p. 48 - 50 (2007/10/02)

Apparent separation of 1.1 or higher on Chirasil Val III can be obtained for Nα-acyl N-alkyl aminoacid amides allowing the use of short capillary gas chromatographic columns.A clean derivatization protocol without racemization is described, proceding through the NCA derivatives that are prepared from "in situ" silylated amino acids with trimethylsilyl cyanide.
