Check Digit Verification of cas no

The CAS Registry Mumber 142913-11-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,1 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 142913-11:
(8*1)+(7*4)+(6*2)+(5*9)+(4*1)+(3*3)+(2*1)+(1*1)=109
109 % 10 = 9
So 142913-11-9 is a valid CAS Registry Number.

Antimicrobial activity of p-hydroxyphenyl acrylate derivatives

Jung, Hee Kim,Park, Eun-Soo,Jae, Hun Shim,Kim, Mal-Nam,Moon, Woong-Sik,Chung, Kyoo-Hyun,Yoon, Jin-San

, p. 7480 - 7483 (2004)

To estimate the antimicrobial effect of p-hydroxyphenyl acrylate (H5) derivatives on the basis of their molecular structure, the hydroxy and acryl groups of p-hydroxyphenyl acrylate were modified. The antimicrobial activity of the resulting compounds was assessed against a Gram-positive bacterium (Staphylococcus aureus), a Gram-negative bacterium (Pseudomonas aeruginosa), and fungi (Aspergillus fumigatus and Penicillium pinphilum) by the halo zone and the shake flask test. The antimicrobial activity of H5 was ascribed mainly to the acryl group. Compounds with acryl or acryloxy groups bound to the phenyl moiety were found to exhibit particularly high antimicrobial activities. The activities of phenyl acrylate and phenyl vinyl ketone were excellent as compared to aliphatic acrylates such as cyclohexyl acrylate and hexyl acrylate, indicating that the stereoelectronic effect of the phenyl group was important to the antimicrobial activity.
