Check Digit Verification of cas no

The CAS Registry Mumber 76704-05-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,0 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76704-05:
(7*7)+(6*6)+(5*7)+(4*0)+(3*4)+(2*0)+(1*5)=137
137 % 10 = 7
So 76704-05-7 is a valid CAS Registry Number.
