Check Digit Verification of cas no

The CAS Registry Mumber 1413942-63-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,3,9,4 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1413942-63:
(9*1)+(8*4)+(7*1)+(6*3)+(5*9)+(4*4)+(3*2)+(2*6)+(1*3)=148
148 % 10 = 8
So 1413942-63-8 is a valid CAS Registry Number.

Novel aminoimidazole derived proline organocatalysts for aldol reactions

Tang, Gongkun,Guen, Uemit,Altenbach, Hans-Josef

, p. 10230 - 10235,6 (2012)

A series of l-proline amides with 2-aminoimidazole have been synthesized and found to be highly efficient organocatalysts for aldol reactions when an appropriate acid was added to control and activate the acceptor carbonyl group. Under optimized reaction conditions, high yields (over 80%) and high selectivities (ee 98%, de 98/2) were obtained in intermolecular aldol reaction even with only 1 equiv of ketone. Likewise, these systems also can catalyze intramolecular aldol reactions with good results.
