Check Digit Verification of cas no
The CAS Registry Mumber 84255-13-0 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 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 84255-13:
(7*8)+(6*4)+(5*2)+(4*5)+(3*5)+(2*1)+(1*3)=130
130 % 10 = 0
So 84255-13-0 is a valid CAS Registry Number.
