Check Digit Verification of cas no

The CAS Registry Mumber 1190880-27-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,8,8 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1190880-27:
(9*1)+(8*1)+(7*9)+(6*0)+(5*8)+(4*8)+(3*0)+(2*2)+(1*7)=163
163 % 10 = 3
So 1190880-27-3 is a valid CAS Registry Number.

Niobium Pentachloride Mediated (Hetero)aromatic Aldehyde Friedel-Crafts Hydroxyalkylation with Arenes: An Efficient Strategy to Synthesize Triarylmethanes

Baviera, Giovanni S.,Donate, Paulo M.,Matias, Alexandre A.,Previdi, Daniel,Rodrigues, Shirley M. M.

, p. 4498 - 4506 (2019/11/21)

Niobium pentachloride is an efficient and useful Lewis acid to conduct Friedel-Crafts hydroxyalkylation between arenes and (hetero)aromatic aldehydes, to generate triarylmethanes. This practical methodology offers several advantages, such as short reaction time, mild experimental conditions, and excellent yields.

A new practical synthesis of triaryl and trisindolylmethanes under solvent-free reaction conditions

Barbero, Margherita,Cadamuro, Silvano,Dughera, Stefano,Magistris, Claudio,Venturello, Paolo

supporting information; experimental part, p. 8393 - 8399 (2012/04/04)

An efficient and practical synthesis of triaryl and trisindolylmethanes is reported via the bisarylation of aryl aldehydes with activated arenes. The new method features mild solvent-free reaction conditions, in most cases nearly stoichiometric reagent ra

Regioselective arylations of α-amido sulfones with electron-rich arenes through friedel-crafts alkylations catalyzed by ferric chloride hexahydrate: Synthesis of unsymmetrical and bis-symmetrical triarylmethanes

Thirupathi, Ponnaboina,Kim, Sung Soo

experimental part, p. 1798 - 1808 (2010/06/15)

Ferric chloride hexahydrate is a highly efficient catalyst for the regioselective arylation of α-amido sulfones. The products undergo further Friedel-Crafts alkylations with heteroaromatic or electron-rich arenes to afford unsymmetrical or bis-symmetrical
