70090-64-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70090-64-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,0,9 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 70090-64:
(7*7)+(6*0)+(5*0)+(4*9)+(3*0)+(2*6)+(1*4)=101
101 % 10 = 1
So 70090-64-1 is a valid CAS Registry Number.

Tandem Cope-Claisen Rearrangement: Scope and Stereochemistry
Ziegler, Frederick E.,Piwinski, John J.
, p. 7181 - 7190 (2007/10/02)
The complete details of the seminal study on the tandem Cope-Claisen rearrangement are presented.The reaction uses an initial Cope rearrangement to trigger an irreversible Claisen rearrangement.In several cases, the Claisen step drives an unfavorable Cope
