Check Digit Verification of cas no

The CAS Registry Mumber 138890-88-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,9 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138890-88:
(8*1)+(7*3)+(6*8)+(5*8)+(4*9)+(3*0)+(2*8)+(1*8)=177
177 % 10 = 7
So 138890-88-7 is a valid CAS Registry Number.
