Check Digit Verification of cas no

The CAS Registry Mumber 7704-94-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,0 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7704-94:
(6*7)+(5*7)+(4*0)+(3*4)+(2*9)+(1*4)=111
111 % 10 = 1
So 7704-94-1 is a valid CAS Registry Number.
