Check Digit Verification of cas no

The CAS Registry Mumber 203449-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,4,4 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 203449-56:
(8*2)+(7*0)+(6*3)+(5*4)+(4*4)+(3*9)+(2*5)+(1*6)=113
113 % 10 = 3
So 203449-56-3 is a valid CAS Registry Number.

Scaffolded bis-azasugars: A dual warhead approach to glycosidase inhibition

Johns, Brian A.,Johnson, Carl R.

, p. 749 - 752 (2007/10/03)

Double Suzuki coupling was achieved with vinyl bromide 7, synthesized from the bromobenzene microbial oxidation metabolite bromocyclohexadienediol 6 and α,ω-diborane coupling partners derived from the hydroboration of the corresponding diene. Ozonolysis and selective reduction protocols served to provide selectively the α/α or β/β tethered polyhydroxylated piperidine ring systems (bis-azabugars). The C8 linked DMJ analogue 1 showed inhibitory activity against glycosidase enzymes.
