Check Digit Verification of cas no

The CAS Registry Mumber 2025-04-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,2 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2025-04:
(6*2)+(5*0)+(4*2)+(3*5)+(2*0)+(1*4)=39
39 % 10 = 9
So 2025-04-9 is a valid CAS Registry Number.
