1198471-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1198471-20-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,4,7 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1198471-20:
(9*1)+(8*1)+(7*9)+(6*8)+(5*4)+(4*7)+(3*1)+(2*2)+(1*0)=183
183 % 10 = 3
So 1198471-20-3 is a valid CAS Registry Number.

Asymmetric α-aminoxylations of stoichiometric ketones using 2-nitrosotoluene
Jiao, Peng,Yamamoto, Hisashi
experimental part, p. 2685 - 2687 (2010/01/16)
Asymmetric aminoxylations of a stoichiometric amount of ketones were accomplished through O-nitrosoaldol reactions of 2-nitrosotoluene catalyzed by a proline-based tetrazole. The advantages of 2-nitrosotoluene and the tetrazole over nitrosobenzene and pro
