Check Digit Verification of cas no

The CAS Registry Mumber 72177-82-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,1,7 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 72177-82:
(7*7)+(6*2)+(5*1)+(4*7)+(3*7)+(2*8)+(1*2)=133
133 % 10 = 3
So 72177-82-3 is a valid CAS Registry Number.

Preparation of α-aminothioamides from aldehydes

Paventi, Martino,Edward, John T.

, p. 282 - 289 (2007/10/02)

The conversion of aldehydes into α-aminonitriles and thence into imidazolidin-4-thiones has been studied.Hydrolysis of the appropriate imidazolidin-4-thiones gave thioamides of nine naturally occuring α-amino acids.The possible pre-biotic significance of these compounds is discussed.

Heterocycles as Masked Diamide/Dipeptide Equivalents. Formation and Reactions of Substituted 5-(Acylamino)oxazoles as Intermediates en route to the Cyclopeptide Alkaloids

Lipshutz, Bruce H.,Hungate, Randall W.,NcCarthy, Keith E.

, p. 7703 - 7713 (2007/10/02)

A variety of novel 2,4-dialkyl-5-(acylamino)oxazoles have been prepared by using either amide nitriles or diamides/dipeptides as starting materials.Ring closure calls for the use of trifluoroacetic acid/trifluoroacetic acid anhydride or an acid halide in
