Check Digit Verification of cas no

The CAS Registry Mumber 438-98-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 438-98:
(5*4)+(4*3)+(3*8)+(2*9)+(1*8)=82
82 % 10 = 2
So 438-98-2 is a valid CAS Registry Number.

IMPROVED GAS CHROMATOGRAPHIC SEPARATION OF ENANTIOMERIC CARBOHYDRATE DERIVATIVES USING A NEW CHIRAL STATIONARY PHASE

Koenig, Wilfried A.,Mischnick-Luebbecke, Petra,Brassat, Baerbel,Lutz, Sabine,Wenz, Gerhard

, p. 11 - 18 (2007/10/02)

Pentylated cyclomaltohexaose ( α-cyclodextrin ) can be used as a chiral stationary phase for cappilary g.l.c. in the range 40 deg to > 200 deg.Strong enantioselective molecular interactions are observed towards trifluoroacetylated carbohydrates, methyl glycosides, 1,4- and 1,5-anhydroalditols, polyols, and polyhydroxy acid methyl esters.Base-line resolution of enantiomers is achieved after only a few minutes.
