1028303-53-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1028303-53-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,8,3,0 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1028303-53:
(9*1)+(8*0)+(7*2)+(6*8)+(5*3)+(4*0)+(3*3)+(2*5)+(1*3)=108
108 % 10 = 8
So 1028303-53-8 is a valid CAS Registry Number.

Synthesis of thieno[3,2-d]pyrimidine-2,4-diones cyclic and acyclic nucleosides as potential anti HIV agents
Jourdan,Laduree,Robba
, p. 305 - 312 (2007/10/02)
Synthesis of cyclic and acyclic nucleosides was achieved by alkylation of 7-methyl or arylthieno[3,2-d]pyrimidine-2,4-diones following the Vorbruggen and Niedballa's method [1]. After a possible deprotection, potential anti HIV agents were obtained.
