76916-12-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 76916-12-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,1 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 76916-12:
(7*7)+(6*6)+(5*9)+(4*1)+(3*6)+(2*1)+(1*2)=156
156 % 10 = 6
So 76916-12-6 is a valid CAS Registry Number.

Syntheses of Amine Derivatives of Phencyclidine

Johnson, Peter Y.,Pan, Robert,Wen, Jing Quan,Halfman, Clarke J.

, p. 2049 - 2054 (2007/10/02)

3-Aminophencyclidine (5) was synthesized by reduction of 3-nitrophencyclidine (3) using either H2 with Pd/C or Na2S in refluxing methanol.Attempts to isolate 4-aminophencyclidine (2), which we hoped to synthesize by hydrolysis of carbamate 15 which was isolated after reaction of amide 10 under Hofmann conditions employing bromine in CH3O(1-)/CH3OH at -40 deg C, were unsuccessful. 4-Aminomethylphencyclidine (18) was synthesized by LAH reduction of nitrile 13 as well as by reductive amination of aldehyde 20.Nitrile 13 and aldehyde 20 were synthesized from 4-bromophencyclidine (11) as was alcohol 26 which served as a precursor to 4-(2-aminoethyl)phencyclidine (19).Amine 19 was also synthesized by NaBH4 reduction of β-nitrostyrene 29 which was generated from aldehyde 20 by condensation with nitromethane using 1,5-diazabicycloundecene as the base catalyst followed by LAH reduction of resulting 4-(2-nitroethyl)phencyclidine (30).Mass spectra and 13C NMR spectra have been obtained on most of the phencyclidine derivatives.
