Check Digit Verification of cas no
The CAS Registry Mumber 398-71-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,9 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 398-71:
(5*3)+(4*9)+(3*8)+(2*7)+(1*1)=90
90 % 10 = 0
So 398-71-0 is a valid CAS Registry Number.
