Check Digit Verification of cas no

The CAS Registry Mumber 111726-09-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,7,2 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111726-09:
(8*1)+(7*1)+(6*1)+(5*7)+(4*2)+(3*6)+(2*0)+(1*9)=91
91 % 10 = 1
So 111726-09-1 is a valid CAS Registry Number.
