Check Digit Verification of cas no

The CAS Registry Mumber 1012871-89-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,2,8,7 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1012871-89:
(9*1)+(8*0)+(7*1)+(6*2)+(5*8)+(4*7)+(3*1)+(2*8)+(1*9)=124
124 % 10 = 4
So 1012871-89-4 is a valid CAS Registry Number.

A novel (S)-proline-modified task-specific chiral ionic liquid-an amphiphilic recoverable catalyst for direct asymmetric aldol reactions in water

Siyutkin, Dmitriy E.,Kucherenko, Alexander S.,Struchkova, Marina I.,Zlotin, Sergei G.

, p. 1212 - 1216 (2008)

A novel chiral (S)-proline-modified task-specific ionic liquid has been designed and synthesized as an efficient recoverable organocatalyst for the direct asymmetric aldol reaction between cycloalkanones and aromatic aldehydes in the presence of water. The catalyst retains its activity and selectivity over at least five reaction cycles.
