Check Digit Verification of cas no
The CAS Registry Mumber 84253-09-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,5 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84253-09:
(7*8)+(6*4)+(5*2)+(4*5)+(3*3)+(2*0)+(1*9)=128
128 % 10 = 8
So 84253-09-8 is a valid CAS Registry Number.
