640270-82-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 640270-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,2,7 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 640270-82:
(8*6)+(7*4)+(6*0)+(5*2)+(4*7)+(3*0)+(2*8)+(1*2)=132
132 % 10 = 2
So 640270-82-2 is a valid CAS Registry Number.

Isobutene Polymerization Using a Chelating Diborane Co-Initiator

Lewis, Stewart P.,Taylor, Nicholas J.,Piers, Warren E.,Collins, Scott

, p. 14686 - 14687 (2007/10/03)

Lewis acidic diborane 1 (J. Am. Chem. Soc. 1999, 121, 3244?3245) is highly effective for both proton- and cationogen-initiated isobutene polymerization in hydrocarbon media at low temperature. Reactions of diborane 1 with cumyl chloride and cumyl methyl ether were studied by variable-temperature 1H and 19F NMR spectroscopy. At low temperatures stable ion pairs 2a and 2b are formed; at higher temperatures these ion-pairs form phenyl-1,3,3-trimethylindan (3) with concomitant release of HCl to form 1 in the case of 2a or degradation of the anion (2b). Reaction between Ph3C-Cl and diborane 1 resulted in the generation of an ion-pair 4 consisting of the Ph3C cation very weakly associated with the chelated, μ-Cl counteranion as revealed by X-ray crystallography.
