Check Digit Verification of cas no

The CAS Registry Mumber 256639-64-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,6,3 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 256639-64:
(8*2)+(7*5)+(6*6)+(5*6)+(4*3)+(3*9)+(2*6)+(1*4)=172
172 % 10 = 2
So 256639-64-2 is a valid CAS Registry Number.

Synthesis of simple sea cucumber ganglioside analogs

Higuchi, Ryuichi,Mori, Takeshi,Sugata, Tetsuji,Yamada, Koji,Miyamoto, Tomofumi

, p. 3175 - 3178 (2007/10/03)

Two simple sea cucumber ganglioside analogs 8 (NeuAcα2→6 Glcβ 1→1 docosanol) and 9 (NeuAcβ2→6 Glcβ 1→1 docosanol), containing a long-chain alcohol as a mimic of ceramide, have been synthesized. Coupling of the methyl 2-thioglycoside derivative of N-acetylneuraminic acid S with docosyl glucoside derivative 3 afforded the protected ganglioside analogs 6 and 7, which were deprotected to give the corresponding ganglioside analogs 8 and 9, respectively. The 13C-NMR data obtained for these anomers 8 and 9 should prove useful for the determination of anomeric configurations of sialic acid residues in gangliosides.
