185460-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 185460-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,4,6 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 185460-91:
(8*1)+(7*8)+(6*5)+(5*4)+(4*6)+(3*0)+(2*9)+(1*1)=157
157 % 10 = 7
So 185460-91-7 is a valid CAS Registry Number.

Synthesis of difluoromethylthio imidazole from methylthio imidazole
Deprez, Pierre,Vevert, Jean-Paul
, p. 159 - 162 (2007/10/03)
Demethylation of methylthio imidazole 1 via a Pummerer rearrangement onto the corresponding sulfoxide 2 afforded imidazole thiol 4 which was then difluoromethylated with the sodium chlorodifluoroacetate/NaI system in 71% overall yield.
