Check Digit Verification of cas no

The CAS Registry Mumber 139334-84-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,3 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139334-84:
(8*1)+(7*3)+(6*9)+(5*3)+(4*3)+(3*4)+(2*8)+(1*4)=142
142 % 10 = 2
So 139334-84-2 is a valid CAS Registry Number.
