Check Digit Verification of cas no
The CAS Registry Mumber 160139-87-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,1,3 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 160139-87:
(8*1)+(7*6)+(6*0)+(5*1)+(4*3)+(3*9)+(2*8)+(1*7)=117
117 % 10 = 7
So 160139-87-7 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.
