61659-05-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61659-05-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,6,5 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 61659-05:
(7*6)+(6*1)+(5*6)+(4*5)+(3*9)+(2*0)+(1*5)=130
130 % 10 = 0
So 61659-05-0 is a valid CAS Registry Number.

Process for producing 3-formylcyclopentanone derivatives
-
, (2008/06/13)
A novel process for producing 3-formylcyclopentanone derivatives which are useful intermediates for syntheses of five-membered ring compounds such as prostaglandins is disclosed. In the process, 3-formylcyclopentanone derivatives are produced starting fro
