Check Digit Verification of cas no

The CAS Registry Mumber 7698-64-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,9 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7698-64:
(6*7)+(5*6)+(4*9)+(3*8)+(2*6)+(1*4)=148
148 % 10 = 8
So 7698-64-8 is a valid CAS Registry Number.
