Check Digit Verification of cas no

The CAS Registry Mumber 2035-30-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,3 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2035-30:
(6*2)+(5*0)+(4*3)+(3*5)+(2*3)+(1*0)=45
45 % 10 = 5
So 2035-30-5 is a valid CAS Registry Number.
