685513-93-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 685513-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,5,5,1 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 685513-93:
(8*6)+(7*8)+(6*5)+(5*5)+(4*1)+(3*3)+(2*9)+(1*3)=193
193 % 10 = 3
So 685513-93-3 is a valid CAS Registry Number.

Synthesis of functionalized 7-azaindoles via directed ortho-metalations
L'Heureux, Alexandre,Thibault, Carl,Ruel, Réjean
, p. 2317 - 2319 (2007/10/03)
Functionalization at C-5 of 4-fluoro- and 4-chloro-1-triisopropylsilyl-7- azaindole, 1 and 2, respectively, leads to a variety of new substituted 7-azaindole derivatives. We also describe two approaches to introduce functionality at C-6.
