Check Digit Verification of cas no

The CAS Registry Mumber 220339-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,3,3 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 220339-89:
(8*2)+(7*2)+(6*0)+(5*3)+(4*3)+(3*9)+(2*8)+(1*9)=109
109 % 10 = 9
So 220339-89-9 is a valid CAS Registry Number.

Stereocontrolled syntheses of α-C-mannosyltryptophan and its analogues

Nishikawa, Toshio,Koide, Yuya,Kajii, Shigeo,Wada, Kyoko,Ishikawa, Miyuki,Isobe, Minoru

, p. 687 - 700 (2007/10/03)

The total synthesis of α-C-mannosyltryptophan (C-Man-Trp), a naturally occurring C-glycosylamino acid, was achieved from a commercially available α-methyl-D-mannoside in 10 steps including the following key steps: the C-glycosidation of a mannose derivative with a stannylacetylene, Castro indole synthesis, and Sc(ClO4)3-promoted coupling with L-serine-derived aziridine carboxylate. The glucose- and galactose-analogues of C-Man-Trp were also synthesized in a similar manner. Conformational analyses of the synthesized C-glycosyltryptophan and its synthetic intermediate are briefly discussed.

Synthesis of a α-C-mannosyltryptophan derivative, naturally occurring C-glycosyl amino acid found in human ribonuclease 1

Nishikawa, Toshio,Ishikawa, Miyuki,Isobe, Minoru

, p. 123 - 125 (2007/10/03)

The title compound was synthesized from D-mannose, based on a novel C-glycosidation with tinacetylene, Castro-indole synthesis, and amino acid synthesis via dehydrotryptophan. Thieme.
