Check Digit Verification of cas no

The CAS Registry Mumber 109936-51-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,3 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109936-51:
(8*1)+(7*0)+(6*9)+(5*9)+(4*3)+(3*6)+(2*5)+(1*1)=148
148 % 10 = 8
So 109936-51-8 is a valid CAS Registry Number.
