Check Digit Verification of cas no

The CAS Registry Mumber 4119-69-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,1 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4119-69:
(6*4)+(5*1)+(4*1)+(3*9)+(2*6)+(1*9)=81
81 % 10 = 1
So 4119-69-1 is a valid CAS Registry Number.

Solvent-free, low-temperature, selective hydrogenation of polyenes using a bimetallic nanoparticle Ru-Sn catalyst

Hermans, Sophie,Raja, Robert,Thomas, John M.,Johnson, Brian F. G.,Sankar, Gopinathan,Gleeson, David

, p. 1211 - 1215 (2001)

The point of attachment of bimetallic Ru6Sn particles which are anchored to the pore walls of a highly dispersed high-area mesoporous silica is found to be the tin atom, as indicated by in situ and ex situ measurements. This catalyst displays high activity for the low-temperature, selective hydrogenation of cyclic polyenes under solvent-free conditions (see scheme).
