Check Digit Verification of cas no

The CAS Registry Mumber 176665-67-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,6,6 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 176665-67:
(8*1)+(7*7)+(6*6)+(5*6)+(4*6)+(3*5)+(2*6)+(1*7)=181
181 % 10 = 1
So 176665-67-1 is a valid CAS Registry Number.
