Check Digit Verification of cas no

The CAS Registry Mumber 1033047-81-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,3,0,4 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1033047-81:
(9*1)+(8*0)+(7*3)+(6*3)+(5*0)+(4*4)+(3*7)+(2*8)+(1*1)=102
102 % 10 = 2
So 1033047-81-2 is a valid CAS Registry Number.

Room temperature copper-catalyzed 2-functionalization of pyrrole rings by a three-component coupling reaction

Cho, Seung Hwan,Chang, Sukbok

, p. 2836 - 2839 (2008/12/23)

(Chemical Equation Presented) Making rings: A new Cu-catalyzed three-component coupling reaction between 1-alkynes, sulfonyl azides, and pyrrole derivatives has been developed for making 2-functionalized pyrrole rings (see scheme). This C-C bond formation offers high efficiency and selectivity, mild reaction conditions, and a wide substrate scope.
