1608182-25-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1608182-25-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,8,1,8 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1608182-25:
(9*1)+(8*6)+(7*0)+(6*8)+(5*1)+(4*8)+(3*2)+(2*2)+(1*5)=157
157 % 10 = 7
So 1608182-25-7 is a valid CAS Registry Number.

Synthesis of 6-nitro-4-sulfanyl-1H-indole derivatives from 2,4,6-trinitrotoluene
Rozhkov, Vladimir V.
, p. 3595 - 3600 (2014/05/20)
The synthesis of 6-nitro-4-sulfanyl-1H-indoles from 2,4,6-trinitrotoluene (TNT) is described. The first step is the nucleophilic substitution of an ortho-nitro group with a thiol to give the corresponding sulfide. The latter were transformed into the corr
