Check Digit Verification of cas no

The CAS Registry Mumber 675-75-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,7 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 675-75:
(5*6)+(4*7)+(3*5)+(2*7)+(1*5)=92
92 % 10 = 2
So 675-75-2 is a valid CAS Registry Number.
