Check Digit Verification of cas no

The CAS Registry Mumber 127558-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,5,5 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 127558-56:
(8*1)+(7*2)+(6*7)+(5*5)+(4*5)+(3*8)+(2*5)+(1*6)=149
149 % 10 = 9
So 127558-56-9 is a valid CAS Registry Number.
