27171-30-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 27171-30-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,1,7 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 27171-30:
(7*2)+(6*7)+(5*1)+(4*7)+(3*1)+(2*3)+(1*0)=98
98 % 10 = 8
So 27171-30-8 is a valid CAS Registry Number.

Synthesis of novel and enantiomerically pure epoxypropylamine: A divergent route to the chiral β-adrenergic blocking agents

Hou, Xue-Long,Li, Bin-Feng,Dai, Li-Xin

, p. 2319 - 2326 (1999)

The chiral building block (S)-N-benzyl-N-isopropyl-2,3-epoxypropylamine is obtained by means of chlorohydroxylation of allylamine, followed by Jacobsen's hydrolytic kinetic resolution with water. A concise, divergent five-step synthesis of three β-adrenergic blocking agents in high enantiomeric excess using (S)-N-benzyl-N-isopropyl-2,3-epoxypropylamine as the key intermediate is described.
