Check Digit Verification of cas no

The CAS Registry Mumber 7402-25-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,0 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7402-25:
(6*7)+(5*4)+(4*0)+(3*2)+(2*2)+(1*5)=77
77 % 10 = 7
So 7402-25-7 is a valid CAS Registry Number.
