Check Digit Verification of cas no

The CAS Registry Mumber 18071-41-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,0,7 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18071-41:
(7*1)+(6*8)+(5*0)+(4*7)+(3*1)+(2*4)+(1*1)=95
95 % 10 = 5
So 18071-41-5 is a valid CAS Registry Number.

CuCl/TBHP catalyzed synthesis of amides from aldehydes and amines in water

Lu, Shao-Yi,Badsara, Satpal Singh,Wu, Yi-Chun,Reddy, Daggula Mallikarjuna,Lee, Chin-Fa

supporting information, p. 633 - 636 (2016/01/26)

A CuCl/TBHP catalyzed amidation of aldehydes with amine under aqueous media is described. Both aliphatic and aromatic aldehydes coupled with a variety of amines under the reaction conditions employed.

Colloid and nano-sized catalysts in organic synthesis: X. Synthesis of carboxamides by direct amidation of carboxylic acids and transamidation catalyzed by colloid copper

Mokhov,Popov, Yu. V.,Budko

, p. 820 - 826 (2015/06/08)

Abstract It was found that in the presence of colloid copper the direct amidation of some carboxylic acids with primary and secondary amines in benzene with azeotropic distillation of water became possible. The catalyst was proven to be suitable also for transamidation reaction of a number of carboxylic acid amides under mild conditions in solvent-free conditions.

Gold-catalyzed amide synthesis from aldehydes and amines in aqueous medium

Li, Gai-Li,Kung, Karen Ka-Yan,Wong, Man-Kin

supporting information; experimental part, p. 4112 - 4114 (2012/06/16)

An efficient gold-catalyzed amide synthesis from aldehydes and amines in aqueous medium under mild reaction conditions has been developed.

Catalytic transamidation reactions compatible with tertiary amide metathesis under ambient conditions

Stephenson, Nickeisha A.,Zhu, Jiang,Gellman, Samuel H.,Stahl, Shannon S.

experimental part, p. 10003 - 10008 (2009/12/08)

The carbon-nitrogen bond of carboxamides is extremely stable under most conditions. The present study reveals that simple zirconium- and hafnium-amido complexes are highly efficient catalysts for equilibrium-controlled transamidation reactions between sec
