Check Digit Verification of cas no

The CAS Registry Mumber 179930-69-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,9,3 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 179930-69:
(8*1)+(7*7)+(6*9)+(5*9)+(4*3)+(3*0)+(2*6)+(1*9)=189
189 % 10 = 9
So 179930-69-9 is a valid CAS Registry Number.

Synthesis of carbohydrate-based monomers that are precursors for the preparation of stereoregular polyamides

Zamora, Francisca,Bueno, Manuel,Molina, Inmaculada,Orgueira, Hernan A.,Varela, Oscar,Galbis, Juan A.

, p. 1811 - 1818 (1996)

The syntheses of some derivatives of 5-amino-5-deoxy-L-arabinonic acid, 5- amino-5-deoxy-D-xylonic acid and (S)-5-amino-4-hydroxypentanoic acid have been performed in several steps from L-arabinose, D-xylose and (S)-(+)- glutamic acid, respectively. These ω-aminoacids are precursors of bifunctional monomers that could be used for the preparation of optically active polyamides.
