Check Digit Verification of cas no

The CAS Registry Mumber 99863-12-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,6 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99863-12:
(7*9)+(6*9)+(5*8)+(4*6)+(3*3)+(2*1)+(1*2)=194
194 % 10 = 4
So 99863-12-4 is a valid CAS Registry Number.
