130625-80-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130625-80-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,2 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130625-80:
(8*1)+(7*3)+(6*0)+(5*6)+(4*2)+(3*5)+(2*8)+(1*0)=98
98 % 10 = 8
So 130625-80-8 is a valid CAS Registry Number.

Synthesis of macrocycles via allylic radical intermediates. A total synthesis of (-)-zearalenone
Hitchcock, Stephen A.,Pattenden, Gerald
, p. 3641 - 3644 (1990)
A concise synthesis of optically active (-)-zearalenone (1) which uses a novel 14-endo trig macrocyclisation from an allylic radical intermediate (Scheme 1) as a key feature, is described.
