Check Digit Verification of cas no

The CAS Registry Mumber 89395-27-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,9 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89395-27:
(7*8)+(6*9)+(5*3)+(4*9)+(3*5)+(2*2)+(1*7)=187
187 % 10 = 7
So 89395-27-7 is a valid CAS Registry Number.
