27958-09-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27958-09-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,9,5 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 27958-09:
(7*2)+(6*7)+(5*9)+(4*5)+(3*8)+(2*0)+(1*9)=154
154 % 10 = 4
So 27958-09-4 is a valid CAS Registry Number.

AN ASYMMETRIC TOTAL SYNTHESIS OF UNNATURAL (+)-ANISOMYCIN
Meyers, A. I.,Dupre, Brian
, p. 113 - 116 (2007/10/02)
Utilizing the valine-based chiral formamidine of 2,5-dihydropyrrole, enantioselective alkylation with p-methoxybenzyl chloride gave, after several subseguent synthetic manipulations, the unnatural enantiomer, (+)-anisomycin, in 22percent overall yield and
