132111-52-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132111-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,1,1 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 132111-52:
(8*1)+(7*3)+(6*2)+(5*1)+(4*1)+(3*1)+(2*5)+(1*2)=65
65 % 10 = 5
So 132111-52-5 is a valid CAS Registry Number.
