Check Digit Verification of cas no

The CAS Registry Mumber 1152312-13-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,2,3,1 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1152312-13:
(9*1)+(8*1)+(7*5)+(6*2)+(5*3)+(4*1)+(3*2)+(2*1)+(1*3)=94
94 % 10 = 4
So 1152312-13-4 is a valid CAS Registry Number.

Scalable total syntheses of N -linked tryptamine dimers by direct indole-aniline coupling: Psychotrimine and kapakahines B and F

Newhouse, Timothy,Lewis, Chad A.,Eastman, Kyle J.,Baran, Phil S.

, p. 7119 - 7137 (2010)

This report details the invention of a method to enable syntheses of psychotrimine (1) and the kapakahines F and B (2, 3) on a gram scale and in a minimum number of steps. Mechanistic inquiries are presented for the key enabling quaternization of indole at the C3 position by electrophilic attack of an activated aniline species. Excellent chemo-, regio-, and diastereoselectivities are observed for reactions with o-iodoaniline, an indole cation equivalent. Additionally, the scope of this reaction is broad with respect to the tryptamine and aniline components. The anti-cancer profiles of 1-3 have also been evaluated.
