Check Digit Verification of cas no

The CAS Registry Mumber 664364-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,4,3,6 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 664364-31:
(8*6)+(7*6)+(6*4)+(5*3)+(4*6)+(3*4)+(2*3)+(1*1)=172
172 % 10 = 2
So 664364-31-2 is a valid CAS Registry Number.
