125283-92-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125283-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,2,8 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 125283-92:
(8*1)+(7*2)+(6*5)+(5*2)+(4*8)+(3*3)+(2*9)+(1*2)=123
123 % 10 = 3
So 125283-92-3 is a valid CAS Registry Number.

73. Synthesis of (+)-(4S,8R)-8-Epi- and (-)-(4R,8S)-4-Epi-β-bisabolol
Frater, Georg,Mueller, Urs
, p. 653 - 658 (2007/10/02)
The first total enantioselective synthesis of (+)-(4S,8R)-8-epi-β-bisabolol ((+)-1) and of (-)-(4R,8S)-4-epi-β-bisabolol ((-)-1) is reported.The key step in the synthesis is the kinetic resolution of (+-)-5 by means of the Sharpless epoxidation yielding (
