Check Digit Verification of cas no

The CAS Registry Mumber 138644-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,4 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138644-31:
(8*1)+(7*3)+(6*8)+(5*6)+(4*4)+(3*4)+(2*3)+(1*1)=142
142 % 10 = 2
So 138644-31-2 is a valid CAS Registry Number.
