41857-46-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 41857-46-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,8,5 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 41857-46:
(7*4)+(6*1)+(5*8)+(4*5)+(3*7)+(2*4)+(1*6)=129
129 % 10 = 9

Phase-transfer catalyzed addition of hydrogen cyanide to N-substituted hydrazones
Chiba,Okimoto
, p. 209 - 211 (2007/10/02)
In a two-phase system consisting of aqueous sodium cyanide and an inert organic solvent and containing a phase-transfer catalyst, ketone benzoylhydrazones, tosylhydrazones, and methoxycarbonylhydrazones upon addition of acetic acid readily add hydrogen cy
