Check Digit Verification of cas no

The CAS Registry Mumber 139976-01-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,7 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139976-01:
(8*1)+(7*3)+(6*9)+(5*9)+(4*7)+(3*6)+(2*0)+(1*1)=175
175 % 10 = 5
So 139976-01-5 is a valid CAS Registry Number.
