Check Digit Verification of cas no

The CAS Registry Mumber 31479-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,7 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 31479-31:
(7*3)+(6*1)+(5*4)+(4*7)+(3*9)+(2*3)+(1*1)=109
109 % 10 = 9
So 31479-31-9 is a valid CAS Registry Number.

Regioselective Synthesis of Thieno[3,2-b]quinolones by Acylation/Two-Fold Buchwald–Hartwig Reactions

Janke, Julia,Ehlers, Peter,Villinger, Alexander,Langer, Peter

, p. 7255 - 7263 (2019)

A variety of thienoquinolones were synthesized from readily accessible thiophene derivatives by regioselective acylations and subsequent two-fold Buchwald–Hartwig–amination. This cyclization allows a convenient synthesis of biologically and pharmaceutically important thienoquinolones. Several thienoquinolones were synthesized in good to very good yields. The optical properties of the products were studied in detail.
