Check Digit Verification of cas no

The CAS Registry Mumber 86649-78-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,6,4 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 86649-78:
(7*8)+(6*6)+(5*6)+(4*4)+(3*9)+(2*7)+(1*8)=187
187 % 10 = 7
So 86649-78-7 is a valid CAS Registry Number.
