Check Digit Verification of cas no
The CAS Registry Mumber 5098-16-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,9 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5098-16:
(6*5)+(5*0)+(4*9)+(3*8)+(2*1)+(1*6)=98
98 % 10 = 8
So 5098-16-8 is a valid CAS Registry Number.
