Check Digit Verification of cas no

The CAS Registry Mumber 1040308-67-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,3,0 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1040308-67:
(9*1)+(8*0)+(7*4)+(6*0)+(5*3)+(4*0)+(3*8)+(2*6)+(1*7)=95
95 % 10 = 5
So 1040308-67-5 is a valid CAS Registry Number.

An efficient method for the synthesis of 1-benzyl/arylindazole 2-oxides via a bis(dibenzylideneacetone)palladium(0) [Pd(dba)2]/tert-butyl nitrite (TBN)-catalyzed reaction of o-alkynylaniline derivatives with TBN is reported. The overall transfo

A facile copper-catalyzed one-pot domino synthesis of 5,12-dihydroindolo[2, 1- b ]quinazolines

Jiang, Min,Li, Jian,Wang, Feng,Zhao, Yichao,Zhao, Feng,Dong, Xiaochun,Zhao, Weili

supporting information; experimental part, p. 1420 - 1423 (2012/05/05)

A domino synthesis of 5,12-dihydroindolo[2,1-b]quinazoline derivatives via copper-catalyzed Ullmann-type intermolecular C-C and intramolecular C-N couplings is reported. Good yields of various 5,12-dihydroindolo[2,1-b] quinazoline derivatives were obtained. Reaction scopes, limitations, and the reaction mechanism are discussed.
