Check Digit Verification of cas no

The CAS Registry Mumber 18219-16-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,1 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18219-16:
(7*1)+(6*8)+(5*2)+(4*1)+(3*9)+(2*1)+(1*6)=104
104 % 10 = 4
So 18219-16-4 is a valid CAS Registry Number.
