120553-05-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120553-05-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,5,5 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 120553-05:
(8*1)+(7*2)+(6*0)+(5*5)+(4*5)+(3*3)+(2*0)+(1*5)=81
81 % 10 = 1
So 120553-05-1 is a valid CAS Registry Number.

Kumada Arylation of Secondary Amides Enabled by Chromium Catalysis for Unsymmetric Ketone Synthesis under Mild Conditions
Chen, Changpeng,Liu, Pei,Luo, Meiming,Zeng, Xiaoming
, p. 5864 - 5868 (2018/05/29)
The synthesis of aromatic ketones by chromium-catalyzed Kumada arylation of secondary amides with organomagnesium reagents is described. This reaction was enabled by using low-cost chromium(III) salt as a precatalyst, combined with trimethylsilyl chloride
