Check Digit Verification of cas no

The CAS Registry Mumber 74985-57-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,8 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74985-57:
(7*7)+(6*4)+(5*9)+(4*8)+(3*5)+(2*5)+(1*7)=182
182 % 10 = 2
So 74985-57-2 is a valid CAS Registry Number.

1,4-Pentadien-3-ones. A source for selenano 1,2,3-selena and thiadiazoles

Bhaskar Reddy,Somasekhar Reddy,Padmavathi

, p. 3429 - 3437 (2007/10/03)

The 4-Selenanols (2,3) and 4-selenanones (4) were obtained by the reaction of 1,4-pentadien-3-ones (1) with sodium hydrogen selenide under different conditions. The fused 1,2,3-selenadiazoles (6) and 1,2,3-thiadiazoles (7) were prepared from 4 on oxidativ

Preparation and Stereochemistry of Some Substituted 4-Selenanones and 4-Selenanols

Nanjappan, Palaniappan,Ramalingam, Kondareddiar,Herd, Melvin D.,Arjunan, Palanisamy,Berlin, K. Darrell

, p. 4622 - 4629 (2007/10/02)

The preparation of a number of substituted 4-selenanones and four epimeric pairs of 4-selenanols has been described.The configuration and conformation of the 4-selenanones and 4-selenanols were assigned on the basis of IR, 1H NMR, and 13C NMR spectral data, and the selenane ring was shown to be predominantly in the chair form.The dissociation constants of cyanohydrins from six substituted 4-selenanones were measured in 80percent dioxane at 25 deg C, and the results were analyzed in terms of steric parameters in the flattened ring systems.
