Check Digit Verification of cas no

The CAS Registry Mumber 1027319-73-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,3,1 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1027319-73:
(9*1)+(8*0)+(7*2)+(6*7)+(5*3)+(4*1)+(3*9)+(2*7)+(1*3)=128
128 % 10 = 8
So 1027319-73-8 is a valid CAS Registry Number.

An expedient route to the glycine templates (R)- or (S)-N-Cbz-5-phenyl-1,4-oxazin-2-one

Dastlik, Kim A.,Giles, Robin G.F.,Roos, Gregory H.P.

, p. 2525 - 2526 (1996)

An economical and practical route to the title compounds is described. The three step, essentially 'one pot' sequence proceeds in overall yields of up to 80% without the need for chromatography of intermediate isolation.

Highly diastereoselective alkylation of the Dellaria oxazinone template with bifunctional electrophiles

Roos, Gregory H. P.,Dastlik, Kim A.

, p. 2197 - 2208 (2007/10/03)

This study investigates the efficiency of alkylation of the Dellaria oxazinone glycinate template with sensitive bifunctional electrophiles. In addition to improved access to the template, triflate/halide bifunctional combinations provided good yields (85-93%) of highly diastereoselective alkylation products.
