102855-25-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102855-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,8,5 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 102855-25:
(8*1)+(7*0)+(6*2)+(5*8)+(4*5)+(3*5)+(2*2)+(1*5)=104
104 % 10 = 4
So 102855-25-4 is a valid CAS Registry Number.

A FACILE ONE STEP SYNTHESIS OF 4-AMINOINDOLES FROM 5-HALO-4-OXO-4,5,6,7-TETRAHYDROINDOLES
Matsumoto, Masakatsu,Ishida, Yasuko,Hatanaka, Naoto
, p. 1667 - 1674 (2007/10/02)
Reaction of 5-halo-4-oxo-4,5,6,7-tetrahydroindoles with amines initiates the amination of the carbonyl function and ensuing dehydrohalogenation leads to a successful formation of 4-aminoindoles.
