Check Digit Verification of cas no

The CAS Registry Mumber 3200-23-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,0 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3200-23:
(6*3)+(5*2)+(4*0)+(3*0)+(2*2)+(1*3)=35
35 % 10 = 5
So 3200-23-5 is a valid CAS Registry Number.
