651744-36-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 651744-36-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,1,7,4 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 651744-36:
(8*6)+(7*5)+(6*1)+(5*7)+(4*4)+(3*4)+(2*3)+(1*6)=164
164 % 10 = 4
So 651744-36-4 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.
