Check Digit Verification of cas no

The CAS Registry Mumber 1435940-38-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,5,9,4 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1435940-38:
(9*1)+(8*4)+(7*3)+(6*5)+(5*9)+(4*4)+(3*0)+(2*3)+(1*8)=167
167 % 10 = 7
So 1435940-38-7 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.
