Check Digit Verification of cas no

The CAS Registry Mumber 206551-43-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,5,5 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 206551-43:
(8*2)+(7*0)+(6*6)+(5*5)+(4*5)+(3*1)+(2*4)+(1*3)=111
111 % 10 = 1
So 206551-43-1 is a valid CAS Registry Number.
