Check Digit Verification of cas no
The CAS Registry Mumber 200577-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,5,7 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 200577-03:
(8*2)+(7*0)+(6*0)+(5*5)+(4*7)+(3*7)+(2*0)+(1*3)=93
93 % 10 = 3
So 200577-03-3 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.
