Check Digit Verification of cas no

The CAS Registry Mumber 19869-79-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,6 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19869-79:
(7*1)+(6*9)+(5*8)+(4*6)+(3*9)+(2*7)+(1*9)=175
175 % 10 = 5
So 19869-79-5 is a valid CAS Registry Number.
