113123-66-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113123-66-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,1,2 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 113123-66:
(8*1)+(7*1)+(6*3)+(5*1)+(4*2)+(3*3)+(2*6)+(1*6)=73
73 % 10 = 3
So 113123-66-3 is a valid CAS Registry Number.

The Protection of Heterocyclic N-H Groups
Katritzky, Alan R.,Khan, Ghulam R.,Marson, Charles M.
, p. 641 - 644 (2007/10/02)
Pyrrole, indole, carbazole and imidazole have been protected as N- derivatives.Deprotection occured under mild conditions after quaternisation. 3-Bromoindole was prepared by bromination of the protected parent indole.
