Check Digit Verification of cas no
The CAS Registry Mumber 25834-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,3 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25834-80:
(7*2)+(6*5)+(5*8)+(4*3)+(3*4)+(2*8)+(1*0)=124
124 % 10 = 4
So 25834-80-4 is a valid CAS Registry Number.
