Check Digit Verification of cas no
The CAS Registry Mumber 99438-28-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,3 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99438-28:
(7*9)+(6*9)+(5*4)+(4*3)+(3*8)+(2*2)+(1*8)=185
185 % 10 = 5
So 99438-28-5 is a valid CAS Registry Number.

Formal synthesis of leustroducsin B via Reformatsky/Claisen condensation of silyl glyoxylates
Greszler, Stephen N.,Malinowski, Justin T.,Johnson, Jeffrey S.
, p. 3206 - 3209 (2011/08/07)
A formal synthesis of leustroducsin B has been completed. The synthesis relies upon a recently developed Reformatsky/Claisen condensation of silyl glyoxylates and enantioenriched β-lactones that establishes two of the molecule's three core stereocenters and permits further elaboration to an intermediate in Imanishi's synthesis via reliable chemistry (Prasad reduction, asymmetric pentenylation, Mitsunobu inversion).
