764-17-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 764-17-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 764-17:
(5*7)+(4*6)+(3*4)+(2*1)+(1*7)=80
80 % 10 = 0
So 764-17-0 is a valid CAS Registry Number.

Chemical reactivity of 6-diazo-5-oxo-l-norleucine (DON) catalyzed by metalloporphyrins (Fe,Ru)

Le Maux, Paul,Nicolas, Irène,Chevance, Soizic,Simonneaux, Gérard

experimental part, p. 4462 - 4468 (2010/07/06)

The transfer of the metallocarbene derived from N- and O-protected 6-diazo-5-oxo-l-norleucine (DON) catalyzed by metalloporphyrins undergoes dimerization, cyclopropanation, N-H and S-H insertion reactions, respectively. An efficient and direct synthesis of 5-oxo-l-pipecolic acid from DON is described from unprotected 6-diazo-5-oxo-l-norleucine.

The Reaction of Lithium Trimethylsilyldiazomethane with Pyroglutamates - a Facile Synthesis of 6-Diazo-5-oxo-norleucine and Derivatives

Coutts, Ian G. C.,Saint, Robert E.

, p. 3242 - 3246 (2007/10/03)

The reaction of carbamate derivatives of pyroglutamic acid esters with the lithium salt of trimethylsilyldiazomethane below -100 deg C gives good yields of the corresponding substituted 6-diazo-5-oxo-norleucine esters; cleavage of Fmoc-substituted products provides a safe, convenient route to the parent acid.
