19387-83-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19387-83-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,3,8 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19387-83:
(7*1)+(6*9)+(5*3)+(4*8)+(3*7)+(2*8)+(1*3)=148
148 % 10 = 8
So 19387-83-8 is a valid CAS Registry Number.

Preparation, 13C NMR/DFT/IGLO study of benzylic mono- and dications, and attempted preparation of a trication

Olah, George A.,Shamma, Tatyana,Burrichter, Arwed,Rasul, Golam,Prakash, G. K. Surya

, p. 12923 - 12928 (1997)

Substituted benzylic mono- and dications were prepared and investigated by 1H and 13C NMR spectroscopy and DFT/IGLO calculations. Combined experimental and theoretical study suggest that the structure 1a is the major resonance contributor to the 2,4,6-trimethylbenzyl cation 1. Similar results were also found for the 2,4,6-dimethyl-4-tert-butylbenzyl 2 and 2,3,4,5,6- pentamethylbenzyl cation 3. It was found that the structure 4a is the predominant resonance contributor to the overall structure of 2,6- dimethylmesityldiyl dication 4 wherein the dienyl and allylic cation units are insulated from each other. Similar studies indicate structure 5a as the predominant canonical structure for 5-methoxy-2,6-dimethyl-m-xylyldiyl dication 5 wherein the dienyl and oxoallylic cation units are insulated from each other. Attempts to generate the 2,3,5,6-tetramethyl-1,4- dimethylbenzenediyl dication 8 was, however, not successful as were the generation of the 2,4,6-trimethylmesityltriyl trication 10 by ionization of 2,4,6-bis(chloromethyl)-mesitylene. The resulting ion was characterized as a chloromethyl substituted dication 9.
