Check Digit Verification of cas no
The CAS Registry Mumber 2181-98-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,8 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2181-98:
(6*2)+(5*1)+(4*8)+(3*1)+(2*9)+(1*8)=78
78 % 10 = 8
So 2181-98-8 is a valid CAS Registry Number.

Two efficient synthetic protocols were developed for the synthesis of dibenzothiophene and 1,4-dihydrodibenzothiophene using thioaurones and allylic phosphonium salt. Mild reaction conditions, a one-pot procedure, and easily accessible starting materials make these protocols powerful tools for the synthesis of these compounds, which are often used in material and pharmaceutical sciences.
