133185-80-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133185-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,1,8 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133185-80:
(8*1)+(7*3)+(6*3)+(5*1)+(4*8)+(3*5)+(2*8)+(1*0)=115
115 % 10 = 5
So 133185-80-5 is a valid CAS Registry Number.
