59742-51-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59742-51-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,7,4 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 59742-51:
(7*5)+(6*9)+(5*7)+(4*4)+(3*2)+(2*5)+(1*1)=157
157 % 10 = 7
So 59742-51-7 is a valid CAS Registry Number.

Convergent synthesis of the polyene macrolide (-)-roxaticin
Rychnovsky, Scott D.,Hoye, Rebecca C.
, p. 1753 - 1765 (2007/10/02)
(-)-Roxaticin has been synthesized from polyol tetraacetonide 5, which was prepared by a threefold convergent route. Each of the optically pure building blocks (2, 3, and 4) was prepared using a Noyori asymmetric hydrogenation. Sequential alkylation of di
