867038-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 867038-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,7,0,3 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 867038-91:
(8*8)+(7*6)+(6*7)+(5*0)+(4*3)+(3*8)+(2*9)+(1*1)=203
203 % 10 = 3
So 867038-91-3 is a valid CAS Registry Number.

The synthesis of stevastelin B3 (2) and B (5) are described. In a first approach, epoxy cyclodepsipeptide 8 was considered as a promising candidate for the synthesis of the [15]-membered ring members of the stevastelins; however, the oxirane ring opening,
