Check Digit Verification of cas no

The CAS Registry Mumber 527759-06-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,7,7,5 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 527759-06:
(8*5)+(7*2)+(6*7)+(5*7)+(4*5)+(3*9)+(2*0)+(1*6)=184
184 % 10 = 4
So 527759-06-4 is a valid CAS Registry Number.

Amide conformational switching induced by protonation of aromatic substituent

Yamasaki, Ryu,Tanatani, Aya,Azumaya, Isao,Saito, Shoichi,Yamaguchi, Kentaro,Kagechika, Hiroyuki

, p. 1265 - 1267 (2003)

(Matrix presented) Introduction of an electron-withdrawing group on the aromatic ring of N-methylacetanilide decreased the ratio of the cis conformer, and the ratio correlates well with the Hammett σ values of the substituents. These steric properties can be applied to achieve amide conformational swiching by protonation at the aromatic substituent of 4-[bis(dimethylamino)]-N-methylacetanilide or N-[p-(dimethylamino)phenyl]-N-phenylacetamide.
