Check Digit Verification of cas no
The CAS Registry Mumber 103204-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,2,0 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103204-80:
(8*1)+(7*0)+(6*3)+(5*2)+(4*0)+(3*4)+(2*8)+(1*0)=64
64 % 10 = 4
So 103204-80-4 is a valid CAS Registry Number.
