Preparation

The preparation of the tert-Butyl 3S-amino-2,3,4,5-tetrahydro-1H-benaepin-2-one-1-acetate tartrate is as follows:Chiral Resolution Of Highly Pure (+1-T-BUTYLOX CARBONYLMETHYL-3-AMINO- 2, 3, 4N5-TETRAHYDRO-LH-[L] BENZAZEPIN-2-ONE USING Tartaric Acid Part A: Preparation of Highly Pure (S)-L-T-BUTYLOXYCARBONYLMETHYL-3-AMINO- 2,3, 4, 5-Tetrahydro-lh- [l] Benzazepin-2-One Tartrate Salt of Formula V Highly pure 1-t-butyloxycarbonylmethyl-3-amino-2, 3, 4, 5-TETRAHYDRO-LH- BENZAZEPIN-2-ONE of Formula II (5.0 g, 17.24 mmol) was heated in ethanol (12.5 ml) at 50-55°C for 25 minutes. The temperature was further raised to 60-65°C and to this was added a solution of L- (+)-tartaric acid (1.8g, 11.9mmol) in ethanol (7.5ml). The reaction mixture was stirred for 24 hours at 60-65°C, allowed to cool to 35-37°C and filtered at the same temperature to afford the crude product (2.75g, 72%). This was suspended in alcohol (11ml) and stirred at 62-65°C for 3 hours, allowed to cool to 45-47°C and filtered to afford the title compound. Yield: 2.55 g, 93% Purity: 99.87%

Check Digit Verification of cas no

The CAS Registry Mumber 117770-66-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,7,7 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 117770-66:
(8*1)+(7*1)+(6*7)+(5*7)+(4*7)+(3*0)+(2*6)+(1*6)=138
138 % 10 = 8
So 117770-66-8 is a valid CAS Registry Number.
