218960-28-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 218960-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,9,6 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 218960-28:
(8*2)+(7*1)+(6*8)+(5*9)+(4*6)+(3*0)+(2*2)+(1*8)=152
152 % 10 = 2
So 218960-28-2 is a valid CAS Registry Number.

Synthesis of Some Uridine and Cytidine Derivatives
Ahmed, A. F. Sayed
, p. 2880 - 2894 (2007/10/03)
The syntheses of 5-(2''-thienyl) and (3''-thienyl) cytidine derivatives with chloro and azido substituents at the 2-position of the sugar moiety have been achieved. Also, some modified nucleosides were prepared from 5, 6-disubstituted uridine, 5-substitut
