142284-93-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142284-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,2,8 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142284-93:
(8*1)+(7*4)+(6*2)+(5*2)+(4*8)+(3*4)+(2*9)+(1*3)=123
123 % 10 = 3
So 142284-93-3 is a valid CAS Registry Number.

A formal total synthesis of PGA2 using the directed Pauson-Khand reaction
Krafft, Marie E.,Wright, Colin
, p. 151 - 152 (2007/10/02)
3,3a,4,6a-Tetrahydro-2-methoxy-2H-cyclopenta[b]furan-4-methanol 1, a key intermediate in the synthesis of PGA2 2, was prepared via the first example of the use of the directed Pauson-Khand reaction in a natural product synthesis.
