143900-72-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143900-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,0 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143900-72:
(8*1)+(7*4)+(6*3)+(5*9)+(4*0)+(3*0)+(2*7)+(1*2)=115
115 % 10 = 5
So 143900-72-5 is a valid CAS Registry Number.

New chiral blocks for introducing the side chain of HMG-CoA reductase inhibitors
Urabe,Matsuka,Sato
, p. 4183 - 4186 (2007/10/02)
A couple of versatile building blocks (8 and 9) of the side chain portion found in many HMG-CoA reductase inhibitors have been prepared. The successful introduction of the side chain to an aromatic ring by 8 or 9 has been demonstrated.
