Check Digit Verification of cas no

The CAS Registry Mumber 4962-31-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,6 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4962-31:
(6*4)+(5*9)+(4*6)+(3*2)+(2*3)+(1*1)=106
106 % 10 = 6
So 4962-31-6 is a valid CAS Registry Number.

Reactions of alkenes, alkynes, and alkoxyallenes with new polymer-supported electrophilic reagents

Monenschein, Holger,Sourkouni-Argirusi, Georgia,Schubothe, Katherine M.,O'Hare, Thomas,Kirschning, Andreas

, p. 2101 - 2104 (2008/02/09)

(matrix presented) Preparation of new polymer-supported electrophilic reagents that efficiently promote 1,2-haloacetoxylations of alkenes and alkoxyallenes is described. Under very mild conditions and in high yields, alkenes are transformed into α-halo acetates while alkoxyallenes lead to vinyl iodides. In contrast to these results, terminal alkynes commonly afford synthetically valuable 1-iodo-alkynes. ? Technischen Universitaet Clausthal. ? Willamette University.
