Check Digit Verification of cas no
The CAS Registry Mumber 85972-27-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,9,7 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 85972-27:
(7*8)+(6*5)+(5*9)+(4*7)+(3*2)+(2*2)+(1*7)=176
176 % 10 = 6
So 85972-27-6 is a valid CAS Registry Number.

Preparation and Diels-Alder Reactivity of Several New Chalcogen-Halogen Substituted Butadienes
Bridges, Alexander J.,Fischer, John W.
, p. 2954 - 2961 (2007/10/02)
Addition of halogens and pseudohalogens across one ?-bond of 1,4-dichlorobut-2-yne, followed by a 1,4-elimination, is an efficient synthesis of several new polysubstituted butadienes.If the product dienes have a sulfur or selenium substituent they are quite reactive, undergoing cycloaddition with the moderately reactive dienophile methyl vinyl ketone at 20 deg C in the presence of boron trifluoride etherate.The regiochemistry of the cycloadditions was elucidated, and the limitations of the methodology are discussed.
