Check Digit Verification of cas no

The CAS Registry Mumber 140184-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,8 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 140184-19:
(8*1)+(7*4)+(6*0)+(5*1)+(4*8)+(3*4)+(2*1)+(1*9)=96
96 % 10 = 6
So 140184-19-6 is a valid CAS Registry Number.

Multi-catalysis cascade reactions based on the methoxycarbonylketene platform: Diversity-oriented synthesis of functionalized non-symmetrical malonates for agrochemicals and pharmaceuticals

Ramachary, Dhevalapally B.,Venkaiah, Chintalapudi,Reddy, Y. Vijayendar,Kishor, Mamillapalli

supporting information; scheme or table, p. 2053 - 2062 (2009/09/05)

In this paper we describe new multi-catalysis cascade (MCC) reactions for the one-pot synthesis of highly functionalized non-symmetrical malonates. These metal-free reactions are either five-step (olefination/hydrogenation/alkylation/ ketenization/esterif

Efficient synthesis of halo indanones via chlorosulfonic acid mediated Friedel-Crafts cyclization of aryl propionic acids and their use in alkylation reactions

Sharma, Anil K.,Subramani, Amutha V.,Gorman, Christopher B.

, p. 389 - 395 (2007/10/03)

Several halo indanones were synthesized from benzyl Meldrum's acid derivatives in two steps. Although several Lewis acids are effective for the Friedel-Crafts ring-closing reaction on more electron-rich arenes, in the case of the electron-deficient arenes this chemistry is not efficient. Here it is reported that chlorosulfonic acid (used as solvent) is an efficient reagent for cyclization of electron-withdrawing arenes. These molecules are potentially useful for subsequent alkylation reactions. The selective alkylation of 5,7-dibromo indanone is demonstrated using Pd-catalyzed Grignard coupling to provide monoalkylated indanone in good yield.
