Check Digit Verification of cas no

The CAS Registry Mumber 340816-70-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,0,8,1 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 340816-70:
(8*3)+(7*4)+(6*0)+(5*8)+(4*1)+(3*6)+(2*7)+(1*0)=128
128 % 10 = 8
So 340816-70-8 is a valid CAS Registry Number.

Identification of thienopyridine carboxamides as selective binders of HIV-1: Trans Activation Response (TAR) and Rev Response Element (RRE) RNAs

Li, Xue-Dong,Liu, Li,Cheng, Liang

, p. 9191 - 9196 (2019/01/03)

Small organic molecules that can selectively bind to RNA with specificity are relatively rare. Here we report the synthesis, biochemical and structural studies of thienopyridine carboxamide derivatives with the capacity of selectively recognizing and binding with HIV-1 TAR and RRE RNAs that are essential elements for viral replication.

Synthesis and characterization of 6-(aryl)-2-thioxo-1,2-dihydropyridine-3- carbonitriles

Attaby, Fawzy A.,El-Ghandour, Ahmed H.,Sayed, Abdelwahed R.,El Bassuony, Ashraf A.,El-Reedy, Ahmed A.M.

, p. 197 - 221 (2012/06/01)

In the present study, 3-aminothieno[2,3-b]pyridines, pyrido[3′, 2′:4,5]thieno[3,2-d]pyrimidinones, and pyrido[3′,2′:4,5] thieno[3,2-d][1,3]oxazinones were prepared via the reaction of 6-(aryl)-2-thioxo-1,2-dihydropyridine-3-carbonitriles with active-halog
