Check Digit Verification of cas no

The CAS Registry Mumber 1638684-67-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,8,6,8 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1638684-67:
(9*1)+(8*6)+(7*3)+(6*8)+(5*6)+(4*8)+(3*4)+(2*6)+(1*7)=219
219 % 10 = 9
So 1638684-67-9 is a valid CAS Registry Number.

Asymmetric diastereoselective synthesis of spirocyclopropane derivatives of oxindole

Oseka, Maksim,Noole, Artur,Zari, Sergei,Oeeren, Mario,Jaerving, Ivar,Lopp, Margus,Kanger, Tonis

, p. 3599 - 3606 (2014/06/23)

A new asymmetric organocatalytic synthesis of spirocyclopropane oxindoles has been developed. The method is based on the Michael addition of N-Boc-protected 3-chlorooxindole to unsaturated 1,4-dicarbonyl compounds, affording trans-substituted spirocyclopropane oxindole derivatives in high diastereo- and enantioselectivity.
