142913-67-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142913-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,1 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142913-67:
(8*1)+(7*4)+(6*2)+(5*9)+(4*1)+(3*3)+(2*6)+(1*7)=125
125 % 10 = 5
So 142913-67-5 is a valid CAS Registry Number.

Total Synthesis of the Mycotoxin (-)-Zearalenone based on Macrocyclisation using a Cinnamyl Radical Intermediate
Hitchcock, Stephen A.,Pattenden, Gerald
, p. 1323 - 1328 (2007/10/02)
A concise synthesis of optically active (-)-zearalenone, which uses a novel 14-endo-trig macrocyclisation from a cinnamyl radical intermediate onto an α,β-enone electrophore as a key feature, is described.
