Check Digit Verification of cas no

The CAS Registry Mumber 138993-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,9 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138993-56:
(8*1)+(7*3)+(6*8)+(5*9)+(4*9)+(3*3)+(2*5)+(1*6)=183
183 % 10 = 3
So 138993-56-3 is a valid CAS Registry Number.
