Check Digit Verification of cas no
The CAS Registry Mumber 90222-57-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,2 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90222-57:
(7*9)+(6*0)+(5*2)+(4*2)+(3*2)+(2*5)+(1*7)=104
104 % 10 = 4
So 90222-57-4 is a valid CAS Registry Number.

The exocyclic olefin geometry control via Ireland-Claisen rearrangement: Stereoselective total syntheses of Barmumycin and Limazepine e
Smits, Gints,Zemribo, Ronalds
, p. 4406 - 4409 (2013/09/24)
Stereoselective total syntheses of Limazepine E and Barmumycin, potent, naturally occurring antitumor agents, are described. The total syntheses control the olefin geometry via a highly selective chelation-controlled Ireland-Claisen rearrangement of a seven-membered lactone-derived boron enolate for the synthesis of (E)-4-ethylidene proline, a crucial building block for a number of natural products.
