Check Digit Verification of cas no

The CAS Registry Mumber 7689-65-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,8 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7689-65:
(6*7)+(5*6)+(4*8)+(3*9)+(2*6)+(1*5)=148
148 % 10 = 8
So 7689-65-8 is a valid CAS Registry Number.
