183891-94-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 183891-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,8,9 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 183891-94:
(8*1)+(7*8)+(6*3)+(5*8)+(4*9)+(3*1)+(2*9)+(1*4)=183
183 % 10 = 3
So 183891-94-3 is a valid CAS Registry Number.

New efficient catalysts for enantioselective transfer hydrogenations
Puentener, Kurt,Schwink, Lothar,Knochel, Paul
, p. 8165 - 8168 (1996)
New C2-symmetrical diaminoferrocenyl derivatives 3 and 2-amino(sulfonamido)cyclohexanes 4 were found to be highly active ligands for the ruthenium catalyzed asymmetric transfer hydrogenation of ketones. Contrary to many existing catalytic syste
