147438-26-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 147438-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,4,3 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 147438-26:
(8*1)+(7*4)+(6*7)+(5*4)+(4*3)+(3*8)+(2*2)+(1*6)=144
144 % 10 = 4
So 147438-26-4 is a valid CAS Registry Number.

Studies on the chemistry of rapamycin: Novel transformations under Lewis-acid catalysis
Luengo,Konialian,Holt
, p. 991 - 994 (2007/10/02)
The reactivity of rapamycin under mild Lewis-acid catalysis has been investigated. The molecule has been found to be extremely sensitive to basic reagents due to carboxylate elimination β to the C24 ketone. However, transformations normally eff
