Check Digit Verification of cas no

The CAS Registry Mumber 1258509-97-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,5,0 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1258509-97:
(9*1)+(8*2)+(7*5)+(6*8)+(5*5)+(4*0)+(3*9)+(2*9)+(1*7)=185
185 % 10 = 5
So 1258509-97-5 is a valid CAS Registry Number.

Remote stereoinduction in the acylation of fully substituted enolates: Tandem reformatsky/quaternary claisen condensations of silyl glyoxylates and β-lactones

Greszler, Stephen N.,Malinowski, Justin T.,Johnson, Jeffrey S.

, p. 17393 - 17395 (2010)

Reformatsky reagents react sequentially with silyl glyoxylates and β-lactones to give highly functionalized Claisen condensation products. A heretofore undocumented instance of stereochemical 1,4-induction results in efficient transmission of β-lactone st
