3379-65-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3379-65-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,7 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3379-65:
(6*3)+(5*3)+(4*7)+(3*9)+(2*6)+(1*5)=105
105 % 10 = 5
So 3379-65-5 is a valid CAS Registry Number.

p-Phenylene sulfide oligomers and their properties. Ar-S couplings mediated by copper or by fluorine substitutions

Goyot, Olivier,Gingras, Marc

scheme or table, p. 1977 - 1981 (2009/07/05)

A series of monodisperse p-phenylene sulfide oligomers were efficiently synthesized by using a bidirectional growth. A strategy combining Cu-catalyzed Ar-S couplings for small oligomers and fluorine aromatic substitutions by aryl thiolates for longer ones was put forward. The latter method is superior to Cu-catalyzed reactions for longer oligomers. Fluorine chemistry brings some new advantages such as solubility and reactivity. Qualitative crystallinity studies were reported according to the oligomer size and the functional series, by using a microscope equipped with a heating stage and a camera.
