Check Digit Verification of cas no

The CAS Registry Mumber 113917-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,9,1 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 113917-92:
(8*1)+(7*1)+(6*3)+(5*9)+(4*1)+(3*7)+(2*9)+(1*2)=123
123 % 10 = 3
So 113917-92-3 is a valid CAS Registry Number.
