Check Digit Verification of cas no

The CAS Registry Mumber 1361520-77-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,6,1,5,2 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1361520-77:
(9*1)+(8*3)+(7*6)+(6*1)+(5*5)+(4*2)+(3*0)+(2*7)+(1*7)=135
135 % 10 = 5
So 1361520-77-5 is a valid CAS Registry Number.

Synthesis and properties of 5-cyano-substituted nucleoside analog with a donor-donor-acceptor hydrogen-bonding pattern

Kim, Hyo-Joong,Chen, Fei,Benner, Steven A.

, p. 3664 - 3669 (2012/06/04)

6-Aminopyridin-2-ones form Watson-Crick pairs with complementary purine analogues to add a third nucleobase pair to DNA and RNA, if an electron-withdrawing group at position 5 slows oxidation and epimerization. In previous work with a nucleoside analogue trivially named dZ, the electron withdrawing unit was a nitro group. Here, we describe an analogue of dZ (cyano-dZ) having a cyano group instead of a nitro group, including its synthesis, pKa, rates of acid-catalyzed epimerization, and enzymatic incorporation.
