20862-11-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20862-11-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,6 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20862-11:
(7*2)+(6*0)+(5*8)+(4*6)+(3*2)+(2*1)+(1*1)=87
87 % 10 = 7
So 20862-11-7 is a valid CAS Registry Number.

PREPARATION OF OPTICALLY ACTIVE 1-ACETOXY-2-ARYLOXYPROPIONITRILES AND ITS APPLICATION TO A FACILE SYNTHESIS OF (S)-(-)-PROPRANOLOL
Matsuo, Noritada,Ohno, Nobuo
, p. 5533 - 5534 (2007/10/02)
(S)-1-Acetoxy-2-aryloxypropionitriles were synthesized by an asymmetric hydrolysis of the racemates with an enzyme. (S)-Propranolol, a typical β-adrenergic blocker, was synthesized from (S)-1-acetoxy-2-α-naphthyloxypropionitrile in two steps.
