93240-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93240-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,2,4 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 93240-40:
(7*9)+(6*3)+(5*2)+(4*4)+(3*0)+(2*4)+(1*0)=115
115 % 10 = 5
So 93240-40-5 is a valid CAS Registry Number.

SYNTHESIS OF BIOLOGICALLY ACTIVE FLUORESCENT PHORBOL ESTERS
Tran, P. L.,Brienne, M. J.,Malthete, J.,Lacombe, L.
, p. 2371 - 2374 (2007/10/02)
Pure fluorescent derivatives of 12-O-tetradecanoyl phorbol-13-acetate (TPA), labeled in the tetradecanoyl chain, are synthesized by two ways: 1) from both enantiomers of β-N-dansylaminotetradecanoic acid which requires the resolution of the (+/-)β-aminoacid precursor; 2) from an achiral fluorescent chain derived from 3-azatetradecanoic acid.The new phorbol derivatives retain the main biological activity of TPA.
