Check Digit Verification of cas no

The CAS Registry Mumber 845724-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,5,7,2 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 845724-76:
(8*8)+(7*4)+(6*5)+(5*7)+(4*2)+(3*4)+(2*7)+(1*6)=197
197 % 10 = 7
So 845724-76-7 is a valid CAS Registry Number.
