Check Digit Verification of cas no

The CAS Registry Mumber 69557-74-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,5,5 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 69557-74:
(7*6)+(6*9)+(5*5)+(4*5)+(3*7)+(2*7)+(1*4)=180
180 % 10 = 0
So 69557-74-0 is a valid CAS Registry Number.

Palladium-catalyzed reactions of arylboron compounds with carboxylic acid chlorides

Korolev,Bumagin

, p. 364 - 369 (2004)

Reactions of sodium tetraarylborates and arylboronic acids with acyl chlorides in the presence of palladium salts afford non-symmetrical ketones in high yields under mild conditions.

Antimony(V) chloride-benzyltriethylammonium chloride complex as an efficient catalyst for friedel-crafts acylation reactions

Huang, An-Ping,Liu, Xue-Yuan,Li, Lian-Hua,Wu, Xiao-Li,Liu, Wei-Min,Liang, Yong-Min

, p. 599 - 602 (2007/10/03)

A novel catalytic system, the complex of antimony(V) chloride (SbCl 5) and benzyltriethylammonium chloride (TEBA), C6H 5CH2NEt3(SbCl5)2Cl complex, is described for Friedel-Crafts acylation reactions of aromatics with acyl and sulfonyl chlorides. The catalyst has a number of useful characteristics, such as ready access, minimal toxicity, reusability, insensitivity to atmosphere and moisture, rapid acylation with high yield, and ease of operation.

Synthesis of unsymmetric ketones via ligandless Pd-catalyzed reaction of acyl chlorides with organoboranes

Bumagin, Nikolay A.,Korolev, Dmitriy N.

, p. 3057 - 3060 (2007/10/03)

The cross-coupling reaction of sodium tetra-arylborates with acyl chlorides to give high yields of unsymmetric ketones has been carried out at 20°C in the presence of Pd(OAc)2 and Na2CO3 in dry or aqueous acetone. Under aqueous conditions arylboronic acids react smoothly with benzoyl chloride resulting in substituted benzophenones.
