Check Digit Verification of cas no

The CAS Registry Mumber 1071023-32-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,7,1,0,2 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1071023-32:
(9*1)+(8*0)+(7*7)+(6*1)+(5*0)+(4*2)+(3*3)+(2*3)+(1*2)=89
89 % 10 = 9
So 1071023-32-9 is a valid CAS Registry Number.

Practical syntheses of N-acetyl (E)-β-arylenamides

Cai, Zhihua,Liu, Guodu,Jiao, Guangjun,Senanayake, Chris H.,Tang, Wenjun

, p. 3355 - 3360 (2014/01/06)

A facile and practical method for the preparation of (E)-β- arylenamides [(E)-N-(1-arylprop-1-en-2-yl]acetamides] has been developed by reductive acetylation of the corresponding oximes with iron(II) acetate as the reducing reagent. Employment of hexamethylphosphoramide as the solvent was found to be critical for the high E/Z selectivity. The methodology has been applied in efficient syntheses of a key chiral intermediate of tamsulosin by asymmetric hydrogenation. Georg Thieme Verlag Stuttgart . New York.

Enantioselective hydrogenation of (Z)- and (E)-β-arylenamides catalyzed by rhodium complexes of monodentate chiral spiro phosphorous ligands: A new access to chiral β-arylisopropylamines

Zhu, Shou-Fei,Liu, Tao,Yang, Shuang,Song, Song,Zhou, Qi-Lin

supporting information; experimental part, p. 7685 - 7690 (2012/09/07)

A highly enantioselective rhodium-catalyzed hydrogenation of both (Z)- and (E)-β-arylenamides was developed by using monodentate chiral spiro phosphite and phosphine ligands, respectively. The hydrogenation reaction provides an efficient access to optically active β-arylisopropylamines, important building blocks for the synthesis of biologically active compounds.
