54515-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54515-80-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,5,1 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 54515-80:
(7*5)+(6*4)+(5*5)+(4*1)+(3*5)+(2*8)+(1*0)=119
119 % 10 = 9
So 54515-80-9 is a valid CAS Registry Number.

, p. 805 - 811 (2007/10/03)
A new approach to the macrocyclic lactone zearalanone is described utilizing an alkenol and an arene trifluoromethanesulfonate as starting materials. The key step is a Pd(0)-catalyzed cross-coupling of the arene trifluoromethanesulfonate with a 9-alkyl-9-
