217194-92-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 217194-92-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,1,9 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 217194-92:
(8*2)+(7*1)+(6*7)+(5*1)+(4*9)+(3*4)+(2*9)+(1*2)=138
138 % 10 = 8
So 217194-92-8 is a valid CAS Registry Number.

Chiral Mn-salen catalyzed enantiotopic selective C-H oxidation of meso- pyrrolidine derivatives
Punniyamurthy,Miyafuji, Akio,Katsuki, Tsutomu
, p. 8295 - 8298 (1998)
Asymmetric desymmetrization of meso-pyrrolidine derivatives was first effected by enantioselective oxidation of the C-H bond α to the nitrogen atom using Mn-salen complex 1b as a catalyst.
