Check Digit Verification of cas no
The CAS Registry Mumber 133044-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,4 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133044-33:
(8*1)+(7*3)+(6*3)+(5*0)+(4*4)+(3*4)+(2*3)+(1*3)=84
84 % 10 = 4
So 133044-33-4 is a valid CAS Registry Number.
