Check Digit Verification of cas no

The CAS Registry Mumber 205654-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,6,5 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 205654-80:
(8*2)+(7*0)+(6*5)+(5*6)+(4*5)+(3*4)+(2*8)+(1*0)=124
124 % 10 = 4
So 205654-80-4 is a valid CAS Registry Number.
