Check Digit Verification of cas no

The CAS Registry Mumber 138937-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,3 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138937-28:
(8*1)+(7*3)+(6*8)+(5*9)+(4*3)+(3*7)+(2*2)+(1*8)=167
167 % 10 = 7
