3335-25-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3335-25-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,3 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3335-25:
(6*3)+(5*3)+(4*3)+(3*5)+(2*2)+(1*5)=69
69 % 10 = 9
So 3335-25-9 is a valid CAS Registry Number.

Se-Aryl Alkane- or Arenecarboselenothioates: Synthesis and Some Reactions

Kato, Shinzi,Yasui, Eiji,Terashima, Kiyomitsu,Ishihara, Hideharu,Murai, Toshiaki

, p. 3931 - 3942 (2007/10/02)

A series of Se-aryl carboselenothioates 3 (RCSSeAr, R=alkyl, aryl) were synthesized and characterized from the reaction of bis(thioacyl) sulfides 1 with sodium areneselenolates.The thionselenolesters 3 are stable (liquid or crystals) both thermally and to moisture.Reactions of 3 with aliphatic primary and secondary amines gave the corresponding ammonium carbodithioates 8 together with diphenyl diselenide 7.In contrast, treatment with aromatic amines or sodium alcoholates afforded the corresponding thioamides or O-alkyl or O-aryl thionoesters in good yields.The oxidation of 3 with m-chloroperbenzoic acid gave the corresponding sulfides 12 and acyl arylseleno sulfides 13 which are formed by a rearrangement of the ArSe group to the thiocarbonyl sulfur atom.
