Check Digit Verification of cas no

The CAS Registry Mumber 1557036-79-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,5,7,0,3 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1557036-79:
(9*1)+(8*5)+(7*5)+(6*7)+(5*0)+(4*3)+(3*6)+(2*7)+(1*9)=179
179 % 10 = 9
So 1557036-79-9 is a valid CAS Registry Number.

Direct (Het)arylation of fluorinated benzothiadiazoles and benzotriazole with (Het)aryl iodides

He, Chun-Yang,Wu, Cai-Zhi,Qing, Feng-Ling,Zhang, Xingang

, p. 1712 - 1718 (2014/03/21)

A new and controllable method for the preparation of unsymmetrical and symmetrical fluorinated benzothiadiazole (FBT)-arene structures that can be applied in organic optoelectronic materials has been developed. The reaction proceeds under mild reaction conditions with high efficiency and shows excellent functional group compatibility, even toward bromide. Fluorinated benzotriazoles also take part in the reaction.
