Check Digit Verification of cas no
The CAS Registry Mumber 4208-80-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,0 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4208-80:
(6*4)+(5*2)+(4*0)+(3*8)+(2*8)+(1*0)=74
74 % 10 = 4
So 4208-80-4 is a valid CAS Registry Number.
