Check Digit Verification of cas no

The CAS Registry Mumber 167696-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,6,9 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 167696-77:
(8*1)+(7*6)+(6*7)+(5*6)+(4*9)+(3*6)+(2*7)+(1*7)=197
197 % 10 = 7
So 167696-77-7 is a valid CAS Registry Number.
