133914-99-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133914-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,1 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133914-99:
(8*1)+(7*3)+(6*3)+(5*9)+(4*1)+(3*4)+(2*9)+(1*9)=135
135 % 10 = 5
So 133914-99-5 is a valid CAS Registry Number.
