132513-40-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132513-40-7 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, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 132513-40:
(8*1)+(7*3)+(6*2)+(5*5)+(4*1)+(3*3)+(2*4)+(1*0)=87
87 % 10 = 7
So 132513-40-7 is a valid CAS Registry Number.
