Check Digit Verification of cas no

The CAS Registry Mumber 90788-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,8 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90788-39:
(7*9)+(6*0)+(5*7)+(4*8)+(3*8)+(2*3)+(1*9)=169
169 % 10 = 9
So 90788-39-9 is a valid CAS Registry Number.
