Check Digit Verification of cas no

The CAS Registry Mumber 105953-26-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,9,5 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 105953-26:
(8*1)+(7*0)+(6*5)+(5*9)+(4*5)+(3*3)+(2*2)+(1*6)=122
122 % 10 = 2
So 105953-26-2 is a valid CAS Registry Number.

5-Thiopyranoses. Part 8. Sulphur Participation in Displacement Reactions of Sulphonate Esters of 5-Thio-D-ribose and 5-Thio-D-xylose Derivatives

Hughes, Neil A.,Wood, Christopher J.

, p. 695 - 700 (2007/10/02)

The 4-methanesulphonate group of 1,2-O-isopropylidene-3,4-di-O-methylsulphonyl-5-thio-α-D-xylopyranose (3) is displaced by intramolecular attack by sulphur leading to a cyclic episulphonium ion (22) which then reacts with nucleophiles to give ring contrac
