Check Digit Verification of cas no

The CAS Registry Mumber 178208-00-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,2,0 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 178208-00:
(8*1)+(7*7)+(6*8)+(5*2)+(4*0)+(3*8)+(2*0)+(1*0)=139
139 % 10 = 9
So 178208-00-9 is a valid CAS Registry Number.

Generation of threonine- and azathreonine N-carboxy anhydrides from α-hydroxy β-lactams promoted by 2,2,6,6-tetramethylpiperidinyl-1-oxyl (TEMPO) in combination with sodium hypochlorite

Palomo, Claudio,Aizpurua, Jesús M.,Cuevas, Carmen,Urchegui, Raquel,Linden, Anthony

, p. 4400 - 4404 (1996)

A versatile one-pot oxidation-Baeyer-Villiger reaction sequence applied to α-hydroxy β-lactams and promoted by 2,2,6,6-tetramethylpiperidinyl-1-oxyl (TEMPO) leads to α-amino acid N-carboxy anhydrides. The examples reported constitute the first application of TEMPO in a Baeyer-Villiger reaction and provide a way for peptide coupling from non α-amino acid precursors.
