Check Digit Verification of cas no

The CAS Registry Mumber 1608151-56-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,8,1,5 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1608151-56:
(9*1)+(8*6)+(7*0)+(6*8)+(5*1)+(4*5)+(3*1)+(2*5)+(1*6)=149
149 % 10 = 9
So 1608151-56-9 is a valid CAS Registry Number.

Counterion effects in the catalytic stereoselective synthesis of 2,3′-pyrrolidinyl spirooxindoles

Macdonald, Jacob P.,Shupe, Benjamin H.,Schreiber, John D.,Franz, Annaliese K.

, p. 5242 - 5244 (2014/05/06)

A Lewis acid-catalyzed stereoselective [3+2] annulation of crotylsilanes with iminooxindoles is reported to access 2,3′-pyrrolidinyl spirooxindoles with four stereocenters. The addition of NaBArF significantly enhances reactivity, allowing either metal salts or acidic clay to be effective catalysts for the stereoselective reaction. the Partner Organisations 2014.
