Check Digit Verification of cas no

The CAS Registry Mumber 19095-67-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,9 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19095-67:
(7*1)+(6*9)+(5*0)+(4*9)+(3*5)+(2*6)+(1*7)=131
131 % 10 = 1
So 19095-67-1 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.
