Check Digit Verification of cas no

The CAS Registry Mumber 174175-00-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,1,7 and 5 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 174175-00:
(8*1)+(7*7)+(6*4)+(5*1)+(4*7)+(3*5)+(2*0)+(1*0)=129
129 % 10 = 9
So 174175-00-9 is a valid CAS Registry Number.

Synthesis and in vitro investigation of potential antiproliferative monosaccharide–D-secoestrone bioconjugates

Bodnár, Brigitta,Mernyák, Erzsébet,Szabó, Johanna,W?lfling, János,Schneider, Gyula,Zupkó, István,Kupihár, Zoltán,Kovács, Lajos

, p. 1938 - 1942 (2017/04/07)

The syntheses of monosaccharide–D-secoestrone conjugates are reported. They were prepared from 3-(prop-2-inyloxy)-D-secoestrone alcohol or oxime and monosaccharide azides via Cu(I)-catalyzed azide–alkyne cycloaddition reactions (CuAAC). The antiproliferat

Synthesis of 5'-fluoro-5'-deoxy- and 5'-amino-5'-deoxytoyocamycin and sangivamycin and some related derivatives

Sharma,Li,Ledvina,Bobek

, p. 1831 - 1852 (2007/10/02)

A series of 5'-substituted analogs of toyocamycin were prepared by condensation of silylated 4-amino-6-bromo-5-cyanopyrrolo[2,3-d]pyrimidine with protected 5-azido-5-deoxy- or 5-fluoro-5-deoxyribofuranose followed by debromination and deblocking. Alternatively, 5'-azido-5'-deoxytoyocamycin was prepared by azidation of toyocamycin. Conversion of the 5-nitrile function of the toyocamycin derivatives into a carboxamide or a thiocarboxamide gave the corresponding analogs of sangivamycin or thiosangivamycin while reduction of the 5'-azido-5'-deoxy nucleosides provided 5'-amino-5'-deoxy derivatives.
