Check Digit Verification of cas no

The CAS Registry Mumber 1611447-14-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,1,4,4 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1611447-14:
(9*1)+(8*6)+(7*1)+(6*1)+(5*4)+(4*4)+(3*7)+(2*1)+(1*4)=133
133 % 10 = 3
So 1611447-14-3 is a valid CAS Registry Number.

Efficient synthesis of 3 H-indoles enabled by the lead-mediated α-arylation of β-ketoesters or γ-lactams using aryl azides

Zhou, Fei,Driver, Tom G.

, p. 2916 - 2919 (2014/06/23)

The development of a lead-mediated α-arylation reaction between aryl azides and β-ketoesters or γ-lactams that facilitates the formation of 3H-indoles is disclosed. Twenty-five examples are included which demonstrate the generality of this reaction to access aryl azides bearing tetrasubstituted o-alkyl substituents. When paired with a Staudinger reduction, this reaction streamlines the synthesis of functionalized 3H-indoles.
