Check Digit Verification of cas no

The CAS Registry Mumber 631896-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,1,8,9 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 631896-12:
(8*6)+(7*3)+(6*1)+(5*8)+(4*9)+(3*6)+(2*1)+(1*2)=173
173 % 10 = 3
So 631896-12-3 is a valid CAS Registry Number.
