864973-87-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 864973-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,4,9,7 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 864973-87:
(8*8)+(7*6)+(6*4)+(5*9)+(4*7)+(3*3)+(2*8)+(1*7)=235
235 % 10 = 5
So 864973-87-5 is a valid CAS Registry Number.

A stereoselective approach to the synthesis of pseudodistomin D
Haddad, Mansour,Larchevêque, Marc,Tong, Han Min
, p. 6015 - 6017 (2007/10/03)
A stereoselective total synthesis of the core unit of pseudodistomin D, starting from L-serine, is described. The key step is a stereoselective intramolecular Michael reaction in which the piperidine ring is formed with the obtention of 1.
