Check Digit Verification of cas no

The CAS Registry Mumber 74494-01-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,9 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74494-01:
(7*7)+(6*4)+(5*4)+(4*9)+(3*4)+(2*0)+(1*1)=142
142 % 10 = 2
So 74494-01-2 is a valid CAS Registry Number.
