Check Digit Verification of cas no

The CAS Registry Mumber 957137-04-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,1,3 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 957137-04:
(8*9)+(7*5)+(6*7)+(5*1)+(4*3)+(3*7)+(2*0)+(1*4)=191
191 % 10 = 1
So 957137-04-1 is a valid CAS Registry Number.

Enantioselective construction of spirocyclic oxindolic cyclopentanes by palladium-catalyzed trimethylenemethane-[3+2]-cycloaddition

Trost, Barry M.,Cramer, Nicolai,Silverman, Steven M.

, p. 12396 - 12397 (2008/09/16)

The palladium catalyzed [3+2] trimethylenemethane (TMM) cycloaddition is an efficient method for the construction of cyclopentanes. Herein, we report a catalytic asymmetric protocol for the synthesis of spirocyclic oxindolic cyclopentanes in excellent yie
