Check Digit Verification of cas no
The CAS Registry Mumber 206988-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,9,8 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 206988-92:
(8*2)+(7*0)+(6*6)+(5*9)+(4*8)+(3*8)+(2*9)+(1*2)=173
173 % 10 = 3
So 206988-92-3 is a valid CAS Registry Number.

A general and simple strategy for 2-arylethenyl-2'-arylethynyl sulfones (9) and 1,4-diarylbut-1d-en-3-ynes (10) has been developed by the lability of carbon-heteroatom bond in heterocycles, 1,2,3-selenadiazole (3) as the basis.
