Check Digit Verification of cas no

The CAS Registry Mumber 143943-86-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,4 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 143943-86:
(8*1)+(7*4)+(6*3)+(5*9)+(4*4)+(3*3)+(2*8)+(1*6)=146
146 % 10 = 6
So 143943-86-6 is a valid CAS Registry Number.

Nano sulfated titania as solid acid catalyst in direct synthesis of fatty acid amides

Hosseini-Sarvari, Mona,Sodagar, Esmat,Doroodmand, Mohammad Mahdi

supporting information; experimental part, p. 2853 - 2859 (2011/05/17)

Nanosized sulfated titania was prepared by a sol-gel hydrothermal process. X-ray diffraction (XRD), transmission electron, and scanning electron micrographs (TEM and SEM), FT-IR specific surface area, and BET N2 adsorption were employed to characterize the properties of the synthesized sulfated TiO2. The results indicate that both anatase and rutile TiO2 are obtainable. This prepared sulfated titania showed high catalytic activity in direct amidation of fatty acids as well as benzoic acids with various amines under solvent-free conditions.
