Check Digit Verification of cas no

The CAS Registry Mumber 205642-00-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,6,4 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 205642-00:
(8*2)+(7*0)+(6*5)+(5*6)+(4*4)+(3*2)+(2*0)+(1*0)=98
98 % 10 = 8
So 205642-00-8 is a valid CAS Registry Number.
