Calculate Digit Verification of CAS Registry Number 76697-97:
(7*7)+(6*6)+(5*6)+(4*9)+(3*7)+(2*9)+(1*7)=197
197 % 10 = 7
So 76697-97-7 is a valid CAS Registry Number.

Unique zeolite-catalyzed synthesis of nitroketene S,N-acetals

Indrasena Reddy,Bhawal, Baburao M.,Rajappa, Srinivasachari

, p. 2101 - 2108 (2007/10/02)

Dimethyl carbonimidodithioates (4a-g, 7a-c) derived from various primary amines and amino acid esters [glycine, (L)-alanine and (L)-phenylalanine] have been condensed with nitromethane in the presence of the rare-earth exchanged zeolite RE(70%)Na Y to give the S,N-acetals (5a-g, 8a-c). Mercuric chloride catalyzed hydrolysis of these (8a-c) has led to the nitroacetyl derivatives (9a-c). The glycine derivative (7a) gives a dimeric product (11) when heated alone with the zeolite.
