138180-63-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138180-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,1,8 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138180-63:
(8*1)+(7*3)+(6*8)+(5*1)+(4*8)+(3*0)+(2*6)+(1*3)=129
129 % 10 = 9
So 138180-63-9 is a valid CAS Registry Number.

Diastereoselective cycloisomerizations of enediynes via palladium catalysis
Trost,Shi
, p. 12491 - 12509 (2007/10/02)
Considerations of atom economy drive a search for reactions that are simple additions which, performed intramolecularly, are cycloisomerizations. Exposure of acyclic enediynes to a catalyst generated by mixing a Pd(0) complex with acetic acid normally in
