Check Digit Verification of cas no

The CAS Registry Mumber 30649-20-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,6,4 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 30649-20:
(7*3)+(6*0)+(5*6)+(4*4)+(3*9)+(2*2)+(1*0)=98
98 % 10 = 8
So 30649-20-8 is a valid CAS Registry Number.
