3453-40-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3453-40-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,5 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3453-40:
(6*3)+(5*4)+(4*5)+(3*3)+(2*4)+(1*0)=75
75 % 10 = 5
So 3453-40-5 is a valid CAS Registry Number.

Highly active water-soluble palladium catalyst for the regioselective carbonylation of vinyl aromatics to 2-arylpropionic acids

Jayasree,Seayad,Chaudhari

, p. 1239 - 1240 (2007/10/03)

A novel water-soluble Pd complex containing pyridine carboxylate and TPPTS as ligands is a highly active catalyst for the carbonylation of vinyl aromatics under biphasic conditions and provides high regioselectivity to 2- arylpropionic acids.

DIRECT, REGIOSELECTIVE HYDROCARBOXYLATION OF ALKYNES TO SATURATED ACIDS BY COBALT AND NICKEL CATALYSTS UNDER PHASE TRANSFER CONDITIONS

Lee, Jong-Tae,Alper, Howard

, p. 1769 - 1770 (2007/10/02)

Phase transfer catalyzed carbonylation of alkynes in the presence of cobalt chloride, potassium cyanide, and nickel cyanide affords saturated carboxylic acids, with good selectivity observed for the branched-chain isomer.
