1161819-40-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1161819-40-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,1,8,1 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1161819-40:
(9*1)+(8*1)+(7*6)+(6*1)+(5*8)+(4*1)+(3*9)+(2*4)+(1*0)=144
144 % 10 = 4
So 1161819-40-4 is a valid CAS Registry Number.

Process Catalyst Mass Efficiency by Using Proline Tetrazole Column-Flow System

Nakashima, Erika,Yamamoto, Hisashi

, p. 1076 - 1079 (2018)

Generally, organocatalysts are not decomposed during chemical transformation, which is different from traditional metal catalysts. To improve catalytic processes efficiency, various studies have been applied to flow synthesis for organocatalysis. Furtherm

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
