Check Digit Verification of cas no

The CAS Registry Mumber 219539-65-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,5,3 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 219539-65:
(8*2)+(7*1)+(6*9)+(5*5)+(4*3)+(3*9)+(2*6)+(1*5)=158
158 % 10 = 8
So 219539-65-8 is a valid CAS Registry Number.
