133463-55-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133463-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,6 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133463-55:
(8*1)+(7*3)+(6*3)+(5*4)+(4*6)+(3*3)+(2*5)+(1*5)=115
115 % 10 = 5
So 133463-55-5 is a valid CAS Registry Number.
