Check Digit Verification of cas no

The CAS Registry Mumber 188124-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,1,2 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 188124-98:
(8*1)+(7*8)+(6*8)+(5*1)+(4*2)+(3*4)+(2*9)+(1*8)=163
163 % 10 = 3
So 188124-98-3 is a valid CAS Registry Number.
