115117-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115117-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,1,1 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 115117-40:
(8*1)+(7*1)+(6*5)+(5*1)+(4*1)+(3*7)+(2*4)+(1*0)=83
83 % 10 = 3
So 115117-40-3 is a valid CAS Registry Number.

Preparation of α-Amino Hydrazones with Triphenyl(β-phenylhydrazono)phosphorane
Gnichtel, Horst,Sinell, Martin
, p. 919 - 922 (2007/10/02)
By reaction of α-anilinophenones 1a and 1b with triphenyl(β-phenylhydrazono)phosphorane, the (Z) hydrazones (Z)-2 are obtained.However, with phenylhydrazine under proton catalysis, the (E) isomers (E)-2 are formed.
