Check Digit Verification of cas no
The CAS Registry Mumber 8005-30-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,0 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 8005-30:
(6*8)+(5*0)+(4*0)+(3*5)+(2*3)+(1*0)=69
69 % 10 = 9
So 8005-30-9 is a valid CAS Registry Number.
