62458-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62458-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,4,5 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 62458-69:
(7*6)+(6*2)+(5*4)+(4*5)+(3*8)+(2*6)+(1*9)=139
139 % 10 = 9
So 62458-69-9 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
