1207473-67-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1207473-67-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,7,4,7 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1207473-67:
(9*1)+(8*2)+(7*0)+(6*7)+(5*4)+(4*7)+(3*3)+(2*6)+(1*7)=143
143 % 10 = 3
So 1207473-67-3 is a valid CAS Registry Number.

Intramolecular C-H insertion in ring-expanded N-heterocyclic carbenes
Holdroyd, Robert S.,Page, Michael J.,Warren, Mark R.,Whittlesey, Michael K.
, p. 557 - 559 (2010)
Mild heating of the ring-expanded N-heterocyclic carbenes 7-Mes and 6-Mes results in intramolecular insertion of the carbene into an ortho-methyl C-H bond. In the presence of traces of acid, the resulting products ring-open to afford N-alkyl indoles.
