Check Digit Verification of cas no

The CAS Registry Mumber 220098-13-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,0,9 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 220098-13:
(8*2)+(7*2)+(6*0)+(5*0)+(4*9)+(3*8)+(2*1)+(1*3)=95
95 % 10 = 5
So 220098-13-5 is a valid CAS Registry Number.

Synthesis of 6-deoxyheptose derivatives via cyclic sulfates and oxetanes

Vargas-Berenguel, Antonio,Santoyo-Gonzalez, Francisco,Calvo-Asin, Jose A.,Calvo-Flores, Francisco G.,Exposito-Lopez, Juan M.,Hernandez-Mateo, Fernando,Isac-Garcia, Joaquin,Gimenez Martinez, Juan J.

, p. 1778 - 1786 (2007/10/03)

Two approaches for the chain elongation and synthesis of 6-deoxyheptose derivatives are described. The first one is based on the regioselective ring opening of 4,6-cyclic sulfate glycopyranoside derivatives at carbon 6 by cyanide ion. The second approach involves the ring expansion of 5,6-anhydro to 5,7-anhydro sugars and subsequent opening of the resulting oxetane, derivative using acetate ion as nucleophile.
