Check Digit Verification of cas no

The CAS Registry Mumber 1309675-23-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,6,7 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1309675-23:
(9*1)+(8*3)+(7*0)+(6*9)+(5*6)+(4*7)+(3*5)+(2*2)+(1*3)=167
167 % 10 = 7
So 1309675-23-7 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.

supporting information; scheme or table, 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).
