211797-38-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 211797-38-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,7,9 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 211797-38:
(8*2)+(7*1)+(6*1)+(5*7)+(4*9)+(3*7)+(2*3)+(1*8)=135
135 % 10 = 5
So 211797-38-5 is a valid CAS Registry Number.

Synthesis of (-)-erythrodiene via intramolecular Pd-catalyzed Zn-ene reaction
Oppolzer,Flachsmann
, p. 5019 - 5022 (1998)
A highly diastereoselective synthesis of (-)-Erythrodiene was achieved via an intramolecular Pd-catalyzed Zne-ene reaction as the key step. It was found that Pd(OAc)2/Bu3P was a superior catalyst for this reaction to Pd(PPh3)4.
