Check Digit Verification of cas no
The CAS Registry Mumber 111469-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,6 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 111469-11:
(8*1)+(7*1)+(6*1)+(5*4)+(4*6)+(3*9)+(2*1)+(1*1)=95
95 % 10 = 5
So 111469-11-5 is a valid CAS Registry Number.

Synthesis of 2-Alkylputrescines from 3-Alkylpyrroles
Garrido, Daniel O. A.,Buldain, Graciela,Ojea, Maria I.,Frydman, Benjamin
, p. 403 - 407 (2007/10/02)
Acylation of 2-(trichloroacetyl)pyrrole gave the 4-acyl derivatives (from 4-formyl to 4-hexanoyl) in good yields.Alkaline treatment gave corresponding 4-acyl-2-pyrrolecarboxylic acids, were decarboxylated to the 3-acylpyrroles by prior conversion to the 3-acyl-2,4,5-triiodopyrroles followed by hydrogenolysis.The 3-acylpyrroles were reduced by treatment with hydrazine in alkaline medium to the 3-alkylpyrroles.The latter were ring-opened by treatment with hydroxylamine in the presence of bicarbonate to give the dioximes of the corresponding 2-alkylsuccinaldehydes, which were then reduced to the 2-alkylpurescines (1,4-diaminobutanes).Ring-opening of 2,3-dimethylpyrrole followed by reduction of the dioxime gave 1,2-dimethylputrescine; the same sequence gave 1,3-dimethylputrescine from 2,4-dimethylpyrrole, while 3,4-dimethylpyrrole did not ring-open and gave the dioxime of 3,4-dimethylmaleimide.
