4436-84-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4436-84-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4436-84:
(6*4)+(5*4)+(4*3)+(3*6)+(2*8)+(1*4)=94
94 % 10 = 4
So 4436-84-4 is a valid CAS Registry Number.

Regioselective control of the thiocarbonylation of terminal acetylenes with arylthiols catalyzed by Pd(II) and diphosphine ligands

El Ali,Tijani,El-Ghanam,Fettouhi

, p. 1567 - 1570 (2007/10/03)

Control of the regioselective thiocarbonylation of terminal acetylenes 1a-e with arylthiols 2a,b was successfully achieved by using Pd(OAc)2 and 1,4-bis(diphenylphosphino)butane (dppb), or 1,3-bis(diphenylphosphino)propane (dppp), as catalysts.

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.
