Check Digit Verification of cas no

The CAS Registry Mumber 1217549-32-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,5,4 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1217549-32:
(9*1)+(8*2)+(7*1)+(6*7)+(5*5)+(4*4)+(3*9)+(2*3)+(1*2)=150
150 % 10 = 0
So 1217549-32-0 is a valid CAS Registry Number.
