Check Digit Verification of cas no

The CAS Registry Mumber 87641-48-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,4 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87641-48:
(7*8)+(6*7)+(5*6)+(4*4)+(3*1)+(2*4)+(1*8)=163
163 % 10 = 3
So 87641-48-3 is a valid CAS Registry Number.
