Check Digit Verification of cas no

The CAS Registry Mumber 169690-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,6,9 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 169690-99:
(8*1)+(7*6)+(6*9)+(5*6)+(4*9)+(3*0)+(2*9)+(1*9)=197
197 % 10 = 7
So 169690-99-7 is a valid CAS Registry Number.
