Check Digit Verification of cas no

The CAS Registry Mumber 1198473-11-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,4,7 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1198473-11:
(9*1)+(8*1)+(7*9)+(6*8)+(5*4)+(4*7)+(3*3)+(2*1)+(1*1)=188
188 % 10 = 8
So 1198473-11-8 is a valid CAS Registry Number.

Rhodium-catalyzed tandem annulation and (5 + 1) cycloaddition: 3-hydroxy-1,4-enyne as the 5-carbon component

Li, Xiaoxun,Song, Wangze,Tang, Weiping

, p. 16797 - 16800 (2013)

A Rh-catalyzed tandem annulation and (5 + 1) cycloaddition was realized. 3-Hydroxy-1,4-enyne served as the new 5-carbon component for the (5 + 1) cycloaddition. Substituted carbazoles, dibenzofurans, and tricyclic compounds containing a cyclohexadienone moiety could be prepared efficiently. The identification of a byproduct suggests that metal carbene and ketene intermediates may be involved in the (5 + 1) cycloaddition.
