Check Digit Verification of cas no

The CAS Registry Mumber 740784-70-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,0,7,8 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 740784-70:
(8*7)+(7*4)+(6*0)+(5*7)+(4*8)+(3*4)+(2*7)+(1*0)=177
177 % 10 = 7
So 740784-70-7 is a valid CAS Registry Number.
