Check Digit Verification of cas no

The CAS Registry Mumber 156128-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,1,2 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 156128-73:
(8*1)+(7*5)+(6*6)+(5*1)+(4*2)+(3*8)+(2*7)+(1*3)=133
133 % 10 = 3
So 156128-73-3 is a valid CAS Registry Number.

Stereoselective coupling of riboses with metallic salts of aromatic heterocycles

Yokoyama, Masataka,Toyoshima, Hirofumi,Shimizu, Miyuki,Togo, Hideo

, p. 29 - 34 (2007/10/03)

The coupling of 2,3,5-tri-O-benzyl-D-ribofuranose with the magnesium, cadmium and zinc salts of typical aromatic heterocycles can afford the corresponding β-C-nucleosides stereoselectively.Furthermore, the present method can be applied to the synthesis of β-C-deoxynucleosides having N-containing aromatic heterocycles as base moieties.

Synthesis of C-Ribo-nucleosides Having Typical Aromatic Heterocycles as Base Moiety

Yokoyama, Masataka,Toyoshima, Akira,Akiba, Takahiro,Togo, Hideo

, p. 265 - 268 (2007/10/02)

Some C-ribo-nucleosides having typical aromatic heterocycles as base moiety were synthesized from the stereoselective addition of lithium salt of aromatic heterocycles to the protected D-ribose followed by the stereospecific cyclization under Mitsunobu conditions.
