Check Digit Verification of cas no

The CAS Registry Mumber 191083-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,0,8 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 191083-81:
(8*1)+(7*9)+(6*1)+(5*0)+(4*8)+(3*3)+(2*8)+(1*1)=135
135 % 10 = 5
So 191083-81-5 is a valid CAS Registry Number.

2,3-Aziridino-2,3-dideoxy-D-ribono-γ-lactone 5-Phosphonate: Stereocontrolled Synthesis from D-Lyxose and Unusual Aziridine Ring Opening

Dauban, Philippe,Dodd, Robert H.

, p. 4277 - 4284 (1997)

The synthesis of (1R,4S,5S)-N-(benzyloxycarbonyl)-4-[(diethoxyphosphinyl)methyl]-3-oxa-6- azabicyclo[3.1.0]hexan-2-one (23), a new member of the 2,3-aziridino γ-lactone family of compounds, was achieved in 15 steps from D-lyxose. Like all aziridino γ-lactones known so far, 23 reacted with a soft nucleophile (ethanethiol) to give exclusively the product of aziridine ring opening at C-2 (24). On the other hand, hard nucleophiles (alcohols) did not react directly with the aziridine ring of 23 but appeared to promote intramolecular attack of the aziridine ring at C-3 by the C-5 phosphonate group, resulting, after hydrolytic workup, in formation of the 2-amino-3-hydroxy-D-ribono-1,4-lactone derivatives 25 and 26, instead of the expected 2-amino-3-alkoxy-D-xylono-1,4-lactone derivatives.
