Check Digit Verification of cas no
The CAS Registry Mumber 4049-81-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,4 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4049-81:
(6*4)+(5*0)+(4*4)+(3*9)+(2*8)+(1*1)=84
84 % 10 = 4
So 4049-81-4 is a valid CAS Registry Number.

Cyclopymerization polymers from non-conjugated dienes
-
, (2008/06/13)
Novel homopolymer and copolymer compositions produced from the polymerization of non-conjugated dienes have been discovered. The novel compositions are produced by an equally novel process comprising cyclopolymerization of non-conjugated dienes employing reduced valence state Group VIB metal oxide catalyst on porous support. The preferred catalyst comprises carbon monoxide reduced chromium on silica. Copolymers are formed by copolymerization of non-conjugated dienes with 1-alkenes in contact with the activated chromium on silica catalyst. The compositions are useful as lubricants and additives.
