Check Digit Verification of cas no
The CAS Registry Mumber 28718-34-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,1 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28718-34:
(7*2)+(6*8)+(5*7)+(4*1)+(3*8)+(2*3)+(1*4)=135
135 % 10 = 5
So 28718-34-5 is a valid CAS Registry Number.
