Check Digit Verification of cas no
The CAS Registry Mumber 133099-05-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,9 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133099-05:
(8*1)+(7*3)+(6*3)+(5*0)+(4*9)+(3*9)+(2*0)+(1*5)=115
115 % 10 = 5
So 133099-05-5 is a valid CAS Registry Number.
