Check Digit Verification of cas no

The CAS Registry Mumber 688360-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,8,3,6 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 688360-45:
(8*6)+(7*8)+(6*8)+(5*3)+(4*6)+(3*0)+(2*4)+(1*5)=204
204 % 10 = 4
So 688360-45-4 is a valid CAS Registry Number.
