Check Digit Verification of cas no

The CAS Registry Mumber 171367-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,3,6 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 171367-56:
(8*1)+(7*7)+(6*1)+(5*3)+(4*6)+(3*7)+(2*5)+(1*6)=139
139 % 10 = 9
So 171367-56-9 is a valid CAS Registry Number.
