Check Digit Verification of cas no

The CAS Registry Mumber 137000-70-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,0 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137000-70:
(8*1)+(7*3)+(6*7)+(5*0)+(4*0)+(3*0)+(2*7)+(1*0)=85
85 % 10 = 5
So 137000-70-5 is a valid CAS Registry Number.
