133152-39-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133152-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,1,5 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133152-39:
(8*1)+(7*3)+(6*3)+(5*1)+(4*5)+(3*2)+(2*3)+(1*9)=93
93 % 10 = 3
So 133152-39-3 is a valid CAS Registry Number.
