Check Digit Verification of cas no

The CAS Registry Mumber 7278-66-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,7 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7278-66:
(6*7)+(5*2)+(4*7)+(3*8)+(2*6)+(1*6)=122
122 % 10 = 2
So 7278-66-2 is a valid CAS Registry Number.
