Check Digit Verification of cas no
The CAS Registry Mumber 5281-04-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,8 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5281-04:
(6*5)+(5*2)+(4*8)+(3*1)+(2*0)+(1*4)=79
79 % 10 = 9
So 5281-04-9 is a valid CAS Registry Number.
