Check Digit Verification of cas no

The CAS Registry Mumber 91120-75-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,2 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91120-75:
(7*9)+(6*1)+(5*1)+(4*2)+(3*0)+(2*7)+(1*5)=101
101 % 10 = 1
So 91120-75-1 is a valid CAS Registry Number.
