Check Digit Verification of cas no

The CAS Registry Mumber 211804-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,8,0 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 211804-28:
(8*2)+(7*1)+(6*1)+(5*8)+(4*0)+(3*4)+(2*2)+(1*8)=93
93 % 10 = 3
So 211804-28-3 is a valid CAS Registry Number.

Synthesis of methyl α-L-callipeltoside

Smith, Garry R.,Finley IV, John J.,Giuliano, Robert M.

, p. 223 - 227 (1998)

The synthesis of callipeltose, a novel amino sugar with the proposed structure, 4-amino-4,6-dideoxy-2,O-3-C-dimethyl-L-talopyranosyl-3,4- urethane, from L-rhamnose is described. Oxime reduction, carbamate cyclization and selective methylation are key steps. The synthesis supports the assignment of the relative stereochemistry of callipeltose.
