134706-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134706-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,7,0 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 134706-40:
(8*1)+(7*3)+(6*4)+(5*7)+(4*0)+(3*6)+(2*4)+(1*0)=114
114 % 10 = 4
So 134706-40-4 is a valid CAS Registry Number.

Synthesis of rac-Norartemeseol
Kirschning, Andreas,Narjes, Frank,Schaumann, Ernst
, p. 933 - 936 (2007/10/02)
The synthesis of the terpenoid rac-norartemeseol (1b) is accomplished using epoxide ring-opening reactions as key steps.Thus, addition of the thio-substituted allyl anion 2b to ethylene oxide followed by proton-induced cyclisation provides the tetrahydrof
