Check Digit Verification of cas no

The CAS Registry Mumber 3988-52-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,8 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3988-52:
(6*3)+(5*9)+(4*8)+(3*8)+(2*5)+(1*2)=131
131 % 10 = 1
So 3988-52-1 is a valid CAS Registry Number.

Stereoselective direct copper-catalyzed alkenylation of oxazoles with bromoalkenes

Besselievre, Francois,Piguel, Sandrine,Mahuteau-Betzer, Florence,Grierson, David S.

supporting information; experimental part, p. 4029 - 4032 (2009/06/18)

(Chemical Equation Presented) A copper-catalyzed direct alkenylation of oxazoles with bromoalkenes has been developed. The method is both regio- and stereoselective and tolerates a variety of functional groups. A wide range of 2-E-vinyl-substituted oxazoles were obtained in high yields including the highly fluorescent alkaloid annuloline.
