Check Digit Verification of cas no

The CAS Registry Mumber 1374507-99-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,5,0 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1374507-99:
(9*1)+(8*3)+(7*7)+(6*4)+(5*5)+(4*0)+(3*7)+(2*9)+(1*9)=179
179 % 10 = 9
So 1374507-99-9 is a valid CAS Registry Number.

In situ anionic shielding for regioselective metalation: Directed peri and iterative metalation routes to polyfunctionalized 7-azaindoles

Schneider, Cedric,David, Emilie,Toutov, Anton A.,Snieckus, Victor

, p. 2722 - 2726 (2012/04/17)

Strolling the ring: A general regioselective directed peri(C4)-metalation route to 1 through an in situ N-anionic protection of C2 is reported. The azaindoles may be elaborated by directed ortho metalation (DoM) and Suzuki coupling to more complex heterocyclic systems. An iterative ring-walk DoM sequence furnishes the exhaustively substituted 2. DMG=directed metalation group, TMEDA=N,N,N′,N′-tetramethylethylenediamine, TMS=trimethylsilyl. Copyright
