Check Digit Verification of cas no

The CAS Registry Mumber 87771-70-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,7 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87771-70:
(7*8)+(6*7)+(5*7)+(4*7)+(3*1)+(2*7)+(1*0)=178
178 % 10 = 8
So 87771-70-8 is a valid CAS Registry Number.
