87892-64-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87892-64-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,9 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 87892-64:
(7*8)+(6*7)+(5*8)+(4*9)+(3*2)+(2*6)+(1*4)=196
196 % 10 = 6
So 87892-64-6 is a valid CAS Registry Number.

Silver(I) Ion Mediatied Desulfurization-Condensation of Thiocarbonyl Compounds with Several Nucleophiles

Shibuya, Isao,Taguchi, Yoichi,Tsuchiya, Tohru,Oishi, Akihiro,Katoh, Eisaku

, p. 3048 - 3052 (2007/10/02)

The desulfurization-condensation reaction was investigated in the presence of silver(I) salt for several kinds of thiocarbonyl compounds with nucleophiles.Such thiocarbonyl compounds as 4,4'-bis(dimethylamino)thiobenzophenone, ethylene trithiocarbonate, and N-(thiobenzoyl)morpholine react with malononitrile or other active methylene compounds in the presence of silver trifluoroacetate to afford the corresponding olefinic compounds together with silver sulfide.This reaction of thiocarbonyl compounds with some other nucleophiles such as aniline derivatives and ethylene glycol, has also afforded imines and 1,3-dioxolane derivatives.
