Check Digit Verification of cas no

The CAS Registry Mumber 200509-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,5,0 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 200509-41:
(8*2)+(7*0)+(6*0)+(5*5)+(4*0)+(3*9)+(2*4)+(1*1)=77
77 % 10 = 7
So 200509-41-7 is a valid CAS Registry Number.
