Check Digit Verification of cas no
The CAS Registry Mumber 8005-03-6 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, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 8005-03:
(6*8)+(5*0)+(4*0)+(3*5)+(2*0)+(1*3)=66
66 % 10 = 6
So 8005-03-6 is a valid CAS Registry Number.
