Check Digit Verification of cas no

The CAS Registry Mumber 854602-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,4,6,0 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 854602-90:
(8*8)+(7*5)+(6*4)+(5*6)+(4*0)+(3*2)+(2*9)+(1*0)=177
177 % 10 = 7
So 854602-90-7 is a valid CAS Registry Number.

β-D-Galactopyranosyl-thiohydroximates and D-galactopyranosylidene- spiro-oxathiazoles: Synthesis and enzymatic evaluation against E. coli D-galactosidase

Elek, Rita,Kiss, Laszlo,Praly, Jean-Pierre,Somsak, Laszlo

, p. 1397 - 1402 (2007/10/03)

By reaction with arylhydroximoyl chlorides, 2,3,4,6-tetra-O-acetyl-1-thio- β-d-galactopyranose was converted to the corresponding β-d- galactopyranosyl-thiohydroximates, which gave predominantly (1S)-d- galactopyranosylidene-spiro-oxathiazoles on illumination in the presence of NBS. Conventional O-deacetylation of both thiohydroximates and oxathiazoles gave weak inhibitors of E. coli d-galactosidase (Ki 1.1-11.1 mM).
