Check Digit Verification of cas no

The CAS Registry Mumber 2248-46-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,4 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2248-46:
(6*2)+(5*2)+(4*4)+(3*8)+(2*4)+(1*6)=76
76 % 10 = 6
So 2248-46-6 is a valid CAS Registry Number.

A convenient synthetic approach to a novel class of aryldifluoromethyl pyrimidine derivatives containing strobilurin motif as insecticidal agents

Hao, Shulin,Cai, Zengfei,Zhang, Wenliang,Cao, Yangyang,Du, Xiaohua

supporting information, p. 88 - 96 (2021/10/07)

A series of aryldifluoromethyl pyrimidine compounds containing strobilurin were synthesized through bioelectronic isometric design with azoxystrobin as the lead compound and a convenient approach to aryldifluoromethylpyrimidine intermediates was developed, which features mild reaction conditions and simple operation. The title compounds and aryldifluoromethylpyrimidine intermediates were characterized by NMR and HRMS. Both 7c and 7l of the preliminary screening tests showed 100% inhibition against Mythimna separata at 100 mg/L. At 20 mg/L, the lethal rate of 7l against Mythimna separata can be up to 80%.

Direct Approach to 3-Fluoroindoles and 3,3-Difluoroindolines from 2,2-Difluoro-2-phenylethan-1-amines via C-H/N-H Coupling

Zhang, Lanfei,Zhang, Xiaofei,Cui, Yongmei,Yang, Chunhao

supporting information, p. 3815 - 3826 (2021/06/28)

Herein, a direct method for the synthesis of 3-fluoroindoles and 3,3-difluoroindolines from easily accessible 2,2-difluoro-2-phenyl ethan-1-amines is presented. This protocol was performed by Pd-catalyzed direct C-H/N-H coupling and employed picolinamide as a directing group. By controlling the temperature for this transformation, various 3,3-difluoroindolines and 3-fluoroindoles could be isolated with moderate to good yields.
