674293-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 674293-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,4,2,9 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 674293-57:
(8*6)+(7*7)+(6*4)+(5*2)+(4*9)+(3*3)+(2*5)+(1*7)=193
193 % 10 = 3
So 674293-57-3 is a valid CAS Registry Number.

Synthesis of spacered nucleoside analogues comprising a difluorocyclopropane moiety
Csuk, René,Thiede, Gisela
, p. 853 - 860 (2007/10/03)
A novel class of difluorinated cyclopropanoic nucleoside analogues containing a propyl spacer between the cyclopropane ring and the heterocycle has been prepared. Some of these compounds showed weak antitumor activity in prelimary screenings. The resoluti
