Check Digit Verification of cas no

The CAS Registry Mumber 88430-77-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,4,3 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 88430-77:
(7*8)+(6*8)+(5*4)+(4*3)+(3*0)+(2*7)+(1*7)=157
157 % 10 = 7
So 88430-77-7 is a valid CAS Registry Number.
