Check Digit Verification of cas no
The CAS Registry Mumber 103173-88-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,1,7 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 103173-88:
(8*1)+(7*0)+(6*3)+(5*1)+(4*7)+(3*3)+(2*8)+(1*8)=92
92 % 10 = 2
So 103173-88-2 is a valid CAS Registry Number.

Intramolecular C-arylation of 2,3,5-tri-O-benzyl- and 2,3,5-tri-O-(3-methylbenzyl)-pentofuranose derivatives.
Martin
, p. 211 - 222 (1987)
Upon treatment with tin(IV) chloride, 1-O-acetyl-2,3,5-tri-O-benzyl- and 1-O-acetyl-2,3,5-tri-O-(3-methylbenzyl)pentofuranose (D-ribo, L-arabino) undergo intramolecular Friedel-Crafts alkylation of the aromatic substituent at O-2 to give unusual internal
