Check Digit Verification of cas no

The CAS Registry Mumber 460348-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,0,3,4 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 460348-38:
(8*4)+(7*6)+(6*0)+(5*3)+(4*4)+(3*8)+(2*3)+(1*8)=143
143 % 10 = 3
So 460348-38-3 is a valid CAS Registry Number.

Convergent stereospecific synthesis of C292 (or LL-Z1640-2), and hypothemycin. Part 1

Sellès, Patrice,Lett, Robert

, p. 4621 - 4625 (2007/10/03)

The stereospecific synthesis of the precursors required for the 14-membered ring formation either via an intramolecular Suzuki coupling or via an intermolecular Suzuki coupling followed by a macrolactonisation is herein reported. One-pot Suzuki couplings were here achieved with vinyldisiamylboranes which were generated in situ from the related chiral precursor. The present convergent approach of C292 (or LL-Z1640-2) and hypothemycin gives a flexible access to related macrolides.
