Check Digit Verification of cas no

The CAS Registry Mumber 281-65-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,8 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 281-65:
(5*2)+(4*8)+(3*1)+(2*6)+(1*5)=62
62 % 10 = 2
So 281-65-2 is a valid CAS Registry Number.
