Check Digit Verification of cas no

The CAS Registry Mumber 1313211-33-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,2,1 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1313211-33:
(9*1)+(8*3)+(7*1)+(6*3)+(5*2)+(4*1)+(3*1)+(2*3)+(1*3)=84
84 % 10 = 4
So 1313211-33-4 is a valid CAS Registry Number.

One-step preparation of gold nanoparticles using 4-acylamidobenzenethiol as a reductive stabilizer

Okamura, Hiroaki,Kurawaki, Junichi,Iwagawa, Tetsuo,Hamada, Toshiyuki,Kawashima, Masatake

, p. 1258 - 1260 (2010)

A simple one-step preparation method to prepare gold nanoparticles (AuNPs) using 4-acylamidobenzenethiol derivatives as reductive stabilizers has been developed. The stabilizers were easily prepared from 4-aminobenzenethiol and dihydroxy fatty acid. By simply mixing the stabilizer and a solution of HAuCl4 in methanol or water, we could form AuNPs spontaneously without any additional reagents or physical treatment. The diameters of the resulting AuNPs were determined to be 25nm using TEM images.
