Check Digit Verification of cas no

The CAS Registry Mumber 1438400-28-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,4,0 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1438400-28:
(9*1)+(8*4)+(7*3)+(6*8)+(5*4)+(4*0)+(3*0)+(2*2)+(1*8)=142
142 % 10 = 2
So 1438400-28-2 is a valid CAS Registry Number.

A Palladium- and Copper-Catalyzed Synthesis of Dihydro[1,2-b]indenoindole-9-ol and Benzofuro[3,2-b]indolines: Metal-Controlled Intramolecular C-C and C-O Bond-Forming Reactions

Boominathan, Siva Senthil Kumar,Wang, Jeh-Jeng

supporting information, p. 17044 - 17050 (2015/11/16)

A palladium- and copper-catalyzed synthesis of dihydro[1,2-b]indenoindole-9-ol and benzofuro[3,2-b]indolines has been developed, whereby the same starting material is employed for the synthesis of both heterocyclic scaffolds and the selectivity of the pro

Ru(ii)-catalyzed intermolecular ortho-C-H amidation of aromatic ketones with sulfonyl azides

Bhanuchandra,Ramu Yadav,Rit, Raja K.,Rao Kuram, Malleswara,Sahoo, Akhila K.

supporting information, p. 5225 - 5227 (2013/06/27)

Ru(ii)-catalyzed intermolecular ortho-C-H amidation of weakly coordinating aromatic ketones with sulfonyl azides is reported. The developed reaction protocol can be extended to various substituted aromatic ketones to afford a wide range of desired C-N bond formation products in good yields.

Ru(ii)-catalyzed intermolecular C-H amidation of weakly coordinating ketones

Zheng, Qing-Zhong,Liang, Yu-Feng,Qin, Chong,Jiao, Ning

supporting information, p. 5654 - 5656 (2013/07/04)

An efficient Ru(ii)-catalyzed intermolecular amidation of weakly coordinating ketones with sulfonyl azides via C-H bond activation is described. The reaction proceeds with high functional group tolerance, providing a novel approach to practical ketone-directed intermolecular C-N bond formation in the absence of an additional oxidant.
