482-21-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 482-21-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,8 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 482-21:
63 % 10 = 3
So 482-21-3 is a valid CAS Registry Number.

Enantioselective synthesis of cryptopleurine and boehmeriasin A via organocatalytic intramolecular aza-Michael addition

Zeng, Chuanqi,Liu, Hanbin,Zhang, Mengyao,Guo, Jiajia,Jiang, Shunchao,Yu, Shouyun

, p. 2251 - 2254,4 (2012)

The enantioselective synthesis of phenanthroquinolizidine alkaloids cryptopleurine and boehmeriasin A was achieved in eight steps from commercial available Cbz-protected 2-piperidinone in 22% and 20% overall yield, respectively. The key steps of this route are intramolecular enantioselective aza-Michael addition, intramolecular aldol addition, and oxidative coupling.
