Check Digit Verification of cas no

The CAS Registry Mumber 644994-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,4,9,9 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 644994-49:
(8*6)+(7*4)+(6*4)+(5*9)+(4*9)+(3*4)+(2*4)+(1*9)=210
210 % 10 = 0
So 644994-49-0 is a valid CAS Registry Number.

Soluble polyisobutylene-supported reusable catalysts for olefin cyclopropanation

Bergbreiter, David E.,Tian, Jianhua

, p. 4499 - 4503 (2007)

Polyisobutylene oligomers (PIB) have been used as soluble supports for the immobilization of cyclopropanation catalysts. In addition to simple carboxylate ligands, chiral bisoxazolines have been successfully attached to these heptane-soluble polymers. The

Reusable nano-sized chiral bisoxazoline catalysts

Ono, Fumiyasu,Kanemasa, Shuji,Tanaka, Junji

, p. 7623 - 7626 (2007/10/03)

The nano-sized gold particle-based chiral catalyst having two kinds of alkyl thiol spacers, one of which is substituted with the chiral bisoxazoline/copper(II) complex at the end, behaves as reusable homogeneous catalyst. This gold particle complex acts as nearly homogeneous catalyst in the ene reaction between 2-phenylpropene and ethyl glyoxylate in dichloromethane, while it undergoes dense aggregation when diluted with hexane so as to be separated by simple filtration. Thus, the catalyst can be recovered after the completion of reaction by the repeated sequences of solvent exchange, centrifugal treatment, and decantation, followed by the recharge of substrates, and the situation is ready for the second reaction.

Chiral ditopic receptors. Application to palladium-catalyzed allylic alkylation

Bourguignon, Jean,Bremberg, Ulf,Dupas, Georges,Hallman, Kristina,Hagberg, Lars,Hortala, Laurent,Levacher, Vincent,Lutsenko, Serghey,Macedo, Emmanuel,Moberg, Christina,Quéguiner, Guy,Rahm, Fredrik

, p. 9583 - 9589 (2007/10/03)

Chiral pyridinooxazoline, quinolinooxazoline, bis(oxazolino)pyridine (pybox), and bisoxazoline (box) derivatives containing crown ether residues were prepared. Some of the ligands were assessed in substrate binding studies and in palladium catalyzed allylic alkylations.
