Check Digit Verification of cas no

The CAS Registry Mumber 1325725-59-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,5,7,2 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1325725-59:
(9*1)+(8*3)+(7*2)+(6*5)+(5*7)+(4*2)+(3*5)+(2*5)+(1*9)=154
154 % 10 = 4
So 1325725-59-4 is a valid CAS Registry Number.

Enantioselective acylation of silyl ketene acetals through fluoride anion-binding catalysis

Birrell, James A.,Desrosiers, Jean-Nicolas,Jacobsen, Eric N.

, p. 13872 - 13875 (2011/10/09)

A highly enantioselective acylation of silyl ketene acetals with acyl fluorides has been developed to generate useful α,α-disubstituted butyrolactone products. This transformation is promoted by a new thiourea catalyst and 4-pyrrolidinopyridine and represents the first example of enantioselective thiourea anion-binding catalysis with fluoride.
