Check Digit Verification of cas no

The CAS Registry Mumber 1338580-08-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,5,8 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1338580-08:
(9*1)+(8*3)+(7*3)+(6*8)+(5*5)+(4*8)+(3*0)+(2*0)+(1*8)=167
167 % 10 = 7
So 1338580-08-7 is a valid CAS Registry Number.
