Check Digit Verification of cas no

The CAS Registry Mumber 99639-16-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,3 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 99639-16:
(7*9)+(6*9)+(5*6)+(4*3)+(3*9)+(2*1)+(1*6)=194
194 % 10 = 4
So 99639-16-4 is a valid CAS Registry Number.
