Check Digit Verification of cas no
The CAS Registry Mumber 433224-00-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,3,2,2 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 433224-00:
(8*4)+(7*3)+(6*3)+(5*2)+(4*2)+(3*4)+(2*0)+(1*0)=101
101 % 10 = 1
So 433224-00-1 is a valid CAS Registry Number.
