Check Digit Verification of cas no

The CAS Registry Mumber 190435-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,4,3 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 190435-72:
(8*1)+(7*9)+(6*0)+(5*4)+(4*3)+(3*5)+(2*7)+(1*2)=134
134 % 10 = 4
So 190435-72-4 is a valid CAS Registry Number.

Synthesis of monosaccharide-fused azetidines

Michaud, Thierry,Chanet-Ray, Josette,Chou, Sithan,Gelas, Jacques

, p. 253 - 269 (1997)

Primary amines reacted upon 4,6-ditosylates of glucopyranosides to give an azetidine ring fused on C-4 and C-6 of the pyranose ring. On the other hand, the 4,6-ditosylate of benzyl mannopyranoside led to the 4,6-diamino-4,6-dideoxy derivative in a good yield. All the compounds and their precursors were identified by 1H and 13C NMR spectroscopy. Assignments of proton signals were made unambiguously using homodecoupling experiments.
