80928-52-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80928-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,2 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80928-52:
(7*8)+(6*0)+(5*9)+(4*2)+(3*8)+(2*5)+(1*2)=145
145 % 10 = 5
So 80928-52-5 is a valid CAS Registry Number.

Total synthesis of vineomycin B2

The first total synthesis of vineomycin B2 (1) has been accomplished. The aglycon segment, a vineomycinone B2 derivative, and the glycon segment, an α-l-acurosyl-l-rhodinose derivative, were prepared via C-glycosylation using an unprotected sugar and powerful chemoselective O-glycosylation using a 2,3-unsaturated sugar, respectively, as the key steps. Furthermore, effective and simultaneous introduction of the two glycon moieties to the aglycon part by concentration-controlled glycosylation led to the total synthesis of 1.
