5173-11-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5173-11-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,7 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5173-11:
(6*5)+(5*1)+(4*7)+(3*3)+(2*1)+(1*1)=75
75 % 10 = 5
So 5173-11-5 is a valid CAS Registry Number.

Pd-catalyzed one-pot sequential unsymmetrical cross-coupling reactions of aryl/heteroaryl 1,2-dihalides

Danodia, Abhinandan K.,Saunthwal, Rakesh K.,Patel, Monika,Tiwari, Rakesh K.,Verma, Akhilesh K.

supporting information, p. 6487 - 6496 (2016/07/15)

Efficient, step-economic, Pd(ii)-catalyzed one-pot sequential Sonogashira/Sonogashira, Sonogashira/Suzuki, Sonogashira/Heck, Suzuki/Sonogashira, Suzuki/Suzuki, Suzuki/Heck, Heck/Sonogashira, Heck/Suzuki and Heck/Heck cross coupling reactions of sterically hindered aryl/heteroaryl 1,2-dihalides have been developed. The present methodology allows the conversion of easily available aryl/heteroaryl 1,2-dihalides into synthetically useful unsymmetrically substituted arenes/heteroarenes in good to excellent yields under mild reaction conditions. This methodology is a powerful tool for building a versatile substrate which can be utilized for the synthesis of various organic scaffolds.
