Check Digit Verification of cas no

The CAS Registry Mumber 198641-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,6,4 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 198641-49:
(8*1)+(7*9)+(6*8)+(5*6)+(4*4)+(3*1)+(2*4)+(1*9)=185
185 % 10 = 5
So 198641-49-5 is a valid CAS Registry Number.
