Check Digit Verification of cas no

The CAS Registry Mumber 319918-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,9,9,1 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 319918-45:
(8*3)+(7*1)+(6*9)+(5*9)+(4*1)+(3*8)+(2*4)+(1*5)=171
171 % 10 = 1
So 319918-45-1 is a valid CAS Registry Number.

Two-step conversions of myo-inositol into (±)-2,3,4,5,6- and 1,3,4,5,6-penta-O-benzyl-myo-inositols are described. Starting from these monohydroxy derivatives of myo-inositol, O-β-L-arabinopyranosyl-(1→2)-sn-myo-inositol from Japanese green tea, Camellia sinensis, and O-α-D-galactopyranosyl-(1→3)-sn-myo-inositol (galactinol) as well as its homolog, O-α-D-galactopyranosyl-(1→6(II))-galactinol, were synthesized by way of the in situ activating glycosylation procedure.
