Check Digit Verification of cas no

The CAS Registry Mumber 344864-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,8,6 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 344864-87:
(8*3)+(7*4)+(6*4)+(5*8)+(4*6)+(3*4)+(2*8)+(1*7)=175
175 % 10 = 5
So 344864-87-5 is a valid CAS Registry Number.
