Check Digit Verification of cas no

The CAS Registry Mumber 88269-45-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,2,6 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 88269-45:
(7*8)+(6*8)+(5*2)+(4*6)+(3*9)+(2*4)+(1*5)=178
178 % 10 = 8
So 88269-45-8 is a valid CAS Registry Number.
