Check Digit Verification of cas no

The CAS Registry Mumber 68690-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,6,9 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 68690-44:
(7*6)+(6*8)+(5*6)+(4*9)+(3*0)+(2*4)+(1*4)=168
168 % 10 = 8
So 68690-44-8 is a valid CAS Registry Number.
