Check Digit Verification of cas no

The CAS Registry Mumber 26774-88-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,7,7 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 26774-88:
(7*2)+(6*6)+(5*7)+(4*7)+(3*4)+(2*8)+(1*8)=149
149 % 10 = 9
So 26774-88-9 is a valid CAS Registry Number.
