1148008-83-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1148008-83-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,8,0,0 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1148008-83:
(9*1)+(8*1)+(7*4)+(6*8)+(5*0)+(4*0)+(3*8)+(2*8)+(1*3)=136
136 % 10 = 6
So 1148008-83-6 is a valid CAS Registry Number.

First total synthesis of the whole series of the antiostatins A and B
Knott, Kerstin E.,Auschill, Stefan,J?ger, Anne,Kn?lker, Hans-Joachim
, p. 1467 - 1469 (2009)
The first synthesis of the whole antiostatin family is described by using an iron-mediated carbazole synthesis, regioselective nitration at C-4 and establishing 5-isobutyl-1-nitrobiuret as a reagent for introduction of the antiostatin B side chain at C-4.
