Check Digit Verification of cas no

The CAS Registry Mumber 7427-77-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,2 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7427-77:
(6*7)+(5*4)+(4*2)+(3*7)+(2*7)+(1*7)=112
112 % 10 = 2
So 7427-77-2 is a valid CAS Registry Number.
