1138242-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1138242-04-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,8,2,4 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1138242-04:
(9*1)+(8*1)+(7*3)+(6*8)+(5*2)+(4*4)+(3*2)+(2*0)+(1*4)=122
122 % 10 = 2
So 1138242-04-2 is a valid CAS Registry Number.

Some reactions of 6,8-dimethoxypyrrolo[3,2,1-hi]indoles
Jumina,Kumar, Naresh,Black, David StC.
experimental part, p. 2059 - 2066 (2009/08/08)
Two 6,8-dimethoxypyrrolo[3,2,1-hi]indole carboxylic esters were hydrolyzed and decarboxylated. In an investigation of their electrophilic substitutions, some pyrroloindoles were formylated using the Vilsmeier reagent, and acylated with oxalyl chloride fol
