Check Digit Verification of cas no

The CAS Registry Mumber 196615-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,6,1 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 196615-29:
(8*1)+(7*9)+(6*6)+(5*6)+(4*1)+(3*5)+(2*2)+(1*9)=169
169 % 10 = 9
So 196615-29-9 is a valid CAS Registry Number.
