Check Digit Verification of cas no

The CAS Registry Mumber 89665-27-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,6 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89665-27:
(7*8)+(6*9)+(5*6)+(4*6)+(3*5)+(2*2)+(1*7)=190
190 % 10 = 0
So 89665-27-0 is a valid CAS Registry Number.
