Check Digit Verification of cas no

The CAS Registry Mumber 139077-40-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,7 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139077-40:
(8*1)+(7*3)+(6*9)+(5*0)+(4*7)+(3*7)+(2*4)+(1*0)=140
140 % 10 = 0
So 139077-40-0 is a valid CAS Registry Number.
