Check Digit Verification of cas no

The CAS Registry Mumber 20998-84-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,9 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20998-84:
(7*2)+(6*0)+(5*9)+(4*9)+(3*8)+(2*8)+(1*4)=139
139 % 10 = 9
So 20998-84-9 is a valid CAS Registry Number.

, (2020)

A straightforward, mild and cost-efficient synthesis of various arylamides in water was accomplished using versatile benzotriazole chemistry. Acylation of various amines was achieved in water at room temperature as well as under microwave irradiation. The developed protocol unfolds the synthesis of amino acid aryl amides, drug conjugates and benzimidazoles. The environmentally friendly synthesis, short reaction time, simple workup, high yields, mild conditions and free of racemization are the key advantages of this protocol.
