Check Digit Verification of cas no

The CAS Registry Mumber 309934-35-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,9,3 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 309934-35:
(8*3)+(7*0)+(6*9)+(5*9)+(4*3)+(3*4)+(2*3)+(1*5)=158
158 % 10 = 8
So 309934-35-8 is a valid CAS Registry Number.
