Check Digit Verification of cas no

The CAS Registry Mumber 1620902-53-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,9,0 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1620902-53:
(9*1)+(8*6)+(7*2)+(6*0)+(5*9)+(4*0)+(3*2)+(2*5)+(1*3)=135
135 % 10 = 5
So 1620902-53-5 is a valid CAS Registry Number.
