132513-38-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132513-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,5,1 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 132513-38:
(8*1)+(7*3)+(6*2)+(5*5)+(4*1)+(3*3)+(2*3)+(1*8)=93
93 % 10 = 3
So 132513-38-3 is a valid CAS Registry Number.
