Check Digit Verification of cas no

The CAS Registry Mumber 137553-84-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,5,5 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137553-84:
(8*1)+(7*3)+(6*7)+(5*5)+(4*5)+(3*3)+(2*8)+(1*4)=145
145 % 10 = 5
So 137553-84-5 is a valid CAS Registry Number.
