Check Digit Verification of cas no

The CAS Registry Mumber 19639-00-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,6,3 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19639-00:
(7*1)+(6*9)+(5*6)+(4*3)+(3*9)+(2*0)+(1*0)=130
130 % 10 = 0
So 19639-00-0 is a valid CAS Registry Number.
