Check Digit Verification of cas no

The CAS Registry Mumber 1262227-20-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,2,2 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1262227-20:
(9*1)+(8*2)+(7*6)+(6*2)+(5*2)+(4*2)+(3*7)+(2*2)+(1*0)=122
122 % 10 = 2
So 1262227-20-2 is a valid CAS Registry Number.

Copper(II)-acid co-catalyzed intermolecular substitution of electron-rich aromatics with diazoesters

Tayama, Eiji,Ishikawa, Moe,Iwamoto, Hajime,Hasegawa, Eietsu

, p. 5159 - 5161 (2012/10/07)

The intermolecular aromatic substitution of N,N-dialkylanilines and alkoxybenzenes with diazoesters is shown to proceed in the presence of catalytic amounts of both copper(II) salt and acid (Lewis or Br?nsted). This method is a mild and rare metal-free C-C bond formation reaction between aromatic (sp2) and aliphatic (sp3) carbons.
