Check Digit Verification of cas no

The CAS Registry Mumber 221141-87-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,1,4 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 221141-87:
(8*2)+(7*2)+(6*1)+(5*1)+(4*4)+(3*1)+(2*8)+(1*7)=83
83 % 10 = 3
So 221141-87-3 is a valid CAS Registry Number.
