Check Digit Verification of cas no

The CAS Registry Mumber 219617-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,6,1 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 219617-77:
(8*2)+(7*1)+(6*9)+(5*6)+(4*1)+(3*7)+(2*7)+(1*7)=153
153 % 10 = 3
So 219617-77-3 is a valid CAS Registry Number.

Fabaceae polysaccharides. III. Galactomannan from astragalus cicer seeds

Olennikov,Rokhin

, p. 165 - 168 (2010)

Seeds of Astragalus cicer L. (Fabaceae) afforded a galactomannan (5.90% yield of seed mass) of molecular weight 1064 kDa, solutions of which had high viscosity [η] 925.5 mL/g and optical activity [α]D +71.9°. The galactomannan consisted of galactose and mannose units in a 1:1.39 ratio. Physicochemical methods established that the main chain of the polysaccharide consisted of 1,4-β-D-mannopyranose units substituted at 72% of the C-6 positions by single α-D-galactopyranose units. The content of variously substituted galactose mannobiose units Man-Man, (Gal)Man-Man/Man- Man(Gal) and (Gal)Man-Man(Gal) in the galactomannan were 18.7, 19.8, and 61.5%, respectively.
