Check Digit Verification of cas no

The CAS Registry Mumber 91178-05-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,7 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91178-05:
(7*9)+(6*1)+(5*1)+(4*7)+(3*8)+(2*0)+(1*5)=131
131 % 10 = 1
So 91178-05-1 is a valid CAS Registry Number.
