Check Digit Verification of cas no

The CAS Registry Mumber 91950-55-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,5 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91950-55:
(7*9)+(6*1)+(5*9)+(4*5)+(3*0)+(2*5)+(1*5)=149
149 % 10 = 9
So 91950-55-9 is a valid CAS Registry Number.
