948-15-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 948-15-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,4 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 948-15:
(5*9)+(4*4)+(3*8)+(2*1)+(1*5)=92
92 % 10 = 2
So 948-15-2 is a valid CAS Registry Number.

Double acylation of alkenes with acylchromates promoted by cationic Pd(II) complex

Yamane, Motoki,Ishibashi, Yuichiro,Sakurai, Hidehiro,Narasaka, Koichi

, p. 174 - 175 (2000)

Double acylation of alkenes such as norbornene and vinyl-silane proceeds by the use of acylchromate complexes and a cationic Pd(II) complex. When two different acylchromates are added successively to a mixture of alkene and the Pd complex, unsymmetrical diketones are obtained almost selectively.

Palladium-catalyzed formal hydroacylation of allenes employing acid chlorides and hydrosilanes

Fujihara, Tetsuaki,Tatsumi, Kenta,Terao, Jun,Tsuji, Yasushi

supporting information, p. 2286 - 2289 (2013/06/05)

The palladium-catalyzed formal hydroacylation of allenes employing acid chlorides and hydrosilanes has been achieved. The reactions proceed with commercially available Pd(OAc)2 as a catalyst and HSi(iPr) 3 as a reducing reagent, giving the corresponding α,β-unsaturated ketones regio- and stereoselectively.
