Check Digit Verification of cas no
The CAS Registry Mumber 220264-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,2,6 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 220264-03:
(8*2)+(7*2)+(6*0)+(5*2)+(4*6)+(3*4)+(2*0)+(1*3)=79
79 % 10 = 9
So 220264-03-9 is a valid CAS Registry Number.

The polyene antibiotic myxalamide A (1) has been prepared by total synthesis. The synthesis illustrates a useful strategy for synthesis in which the high 1,2-stereocontrol achievable with the aldol reaction can be parlayed by other stereoselective process
