Check Digit Verification of cas no

The CAS Registry Mumber 22172-31-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,7 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22172-31:
(7*2)+(6*2)+(5*1)+(4*7)+(3*2)+(2*3)+(1*1)=72
72 % 10 = 2
So 22172-31-2 is a valid CAS Registry Number.
