Check Digit Verification of cas no

The CAS Registry Mumber 1111165-55-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,1,1,6 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1111165-55:
(9*1)+(8*1)+(7*1)+(6*1)+(5*1)+(4*6)+(3*5)+(2*5)+(1*5)=89
89 % 10 = 9
So 1111165-55-9 is a valid CAS Registry Number.

Multicomponent reactions of pyridines, α-bromo carbonyl compounds and silylaryl triflates as aryne precursors: a facile one-pot synthesis of pyrido[2,1-a]isoindoles

Huang, Xian,Zhang, Tiexin

, p. 208 - 211 (2009)

Multicomponent reactions (MCRs) involving pyridines, α-bromo ketones, and silylaryl triflates as aryne precursors were investigated. The reactions could also be extended to isoquinoline or α-bromo ethyl acetate. Substituted pyrido[2,1-a]isoindoles or isoi

Novel synthesis of pyrido[2,1-a]isoindoles via a three-component assembly involving benzynes

Xie, Chunsong,Zhang, Yuhong,Xu, Peixin

experimental part, p. 3115 - 3120 (2009/06/05)

A novel three-component assembly involving benzynes has been developed for the synthesis of pyrido[2,1-a]isoindoles in moderate yields. Reaction conditions have been optimized and the scope of the reaction has been studied. A plausible mechanism has been proposed to account for the three-component reaction.
