Check Digit Verification of cas no

The CAS Registry Mumber 54921-89-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,9,2 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 54921-89:
(7*5)+(6*4)+(5*9)+(4*2)+(3*1)+(2*8)+(1*9)=140
140 % 10 = 0
So 54921-89-0 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.

Trifluoromethanesulfonic acid catalyzed Friedel-Crafts alkylations of 1,2,4-trimethoxybenzene with aldehydes or benzylic alcohols

Wilsdorf, Michael,Leichnitz, Daniel,Reissig, Hans-Ulrich

supporting information, p. 2494 - 2497 (2013/07/05)

Trifluoromethanesulfonic acid in acetonitrile was found to efficiently catalyze Friedel-Crafts alkylations of 1,2,4-trimethoxybenzene with a variety of simple or functionalized aldehydes to provide di- or triarylmethanes in high yields. The operationally

Efficient synthesis of triarylmethanes via bisarylation of aryl aldehydes with arenes catalyzed by silica gel-supported sodium hydrogen sulfate

Leng, Yixin,Chen, Fang,Zuo, Li,Duan, Wenhu

experimental part, p. 2370 - 2373 (2010/06/13)

An efficient synthesis of triarylmethanes has been developed via bisarylation of aryl aldehydes with arenes catalyzed by silica gel-supported sodium hydrogen sulfate in a solvent-free system. The new method features high yield, mild reaction conditions, a
