Check Digit Verification of cas no
The CAS Registry Mumber 66121-72-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,1,2 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66121-72:
(7*6)+(6*6)+(5*1)+(4*2)+(3*1)+(2*7)+(1*2)=110
110 % 10 = 0
So 66121-72-0 is a valid CAS Registry Number.
